Which statement describes a characteristic of most metals?
A.They can be formed into wires.
B.They cannot be shaped by hammering or pounding
C.They are liquid at room temperature
D.They are poor conductors.
Answer:
Answer is A
Explanation:
A on edge
Answer:
A. They can be formed into wires
Explanation:
Metals are also malleable, which means that they can be hammered into very thin sheets without breaking. They are ductile, which means that they can be drawn into wires. When a fresh surface of any metal is exposed, it will be very shiny because it reflects light well. So they can be shaped by hammering or pounding. Metals are not liquids except mercury but most metals are not liquid at room temperature. Metals are actually great conductors/conductibility, which means they have a heat factor in them which most metals do.
Therefore, this shows that A. They can be formed into wires. Is the best choice

A clever octopus swims 8 1/4km at a speed
of 0.5 km/h. How long does the octopus
take to swim this distance in hours and
minutes
Answer:
33 hours or equivalently: 1980 minutes
Explanation:
Use the formula for movement under constant velocity, as the velocity equal the distance traveled divided by the time it took, and solve for the unknown time (t):
[tex]v=\frac{distance}{t} \\t=\frac{distance}{v} \\t=\frac{8.25\,\,km}{0.5 \,\,km/h} \\t = 33 \,\,h[/tex]
which can also be given in minutes as : 33 x 60 = 1980 minutes

A child slides down a hill on a toboggan with acceleration of 1.8 m/s2. if she starts from rest, how far has she traveled in: 2 seconds
Answer:
2.4 m
Explanation:
From the question above,
Applying equation of motion,
s = ut+at²/2....................... Equation 1
Where t = time, u = initial velocity, a = acceleration, s = distance.
make s the subject of the equation,
Given: a = 1.8 m/s², t = 2 seconds, u = 0 m/s (from rest)
Substitute these value into equation 1
s = 0(2)+1.8(2²)/2
s = 1.2(4)/2
s = 2.4 m.
Hence she has traveled 2.4 m
Answer:
4.0m/s

Melissa and Rory live near a bike trail, 21 km apart. They plan to meet at a park mid-way between their homes. They start from their homes at the same moment, and ride toward each other. Both ride at 7 km/hour. Melissa’s dog Jessie knows this routine. He starts with Melissa, and runs at 18 km/hour toward Rory. When he reaches Rory, he turns around and runs toward Melissa. He reaches Melissa, turns around and runs toward Rory again, and so on, until Melissa and Rory meet. How many kilometers did Jessie run?
Answer:
27km.
Explanation:
Jessie will run for a duration of time, which is the time it takes for Melissa and Rory to meet each other.
Together combined, Melissa and Rory runs at 14km/h. The bike trail is 21km, so it will take 1.5 hours.
Jessie runs at 18km/h, so Jessie will run 18 * 1.5 = 27km.
2. How long will it take for a ball thrown vertically upward with an initial velocity of
480 km/h to reach its maximum height?
Answer:
13.33 seconds
Explanation:
At maximum height, the equation of motion becomes:
v = u + at
Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:
v = at
v = 480 km/hr = 133.333 m/s
10t = 133.333
t = 133.333/10
t = 13.33 seconds.
The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is 13.33 seconds.
Titus drives his jetski a distance of 1000 meters in 7.045 seconds. How fast was he moving in meters per second? How fast was he moving in miles per hour?
Answer:
a) v = 141.9 m/s
b) v = 317.4 miles/h
Explanation:
a) How fast was he moving in meters per second?
[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s [/tex]
Hence, the jet ski is moving at 141.9 meters per second.
b) How fast was he moving in miles per hour?
[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s*\frac{3600 s}{1 h}*\frac{1 mile}{1609.34 m} = 317.4 miles/h [/tex]
Therefore, the jet ski is moving at 317.4 miles per hour.

When performing a cranking sound diagnosis, Technician A says that all engines may be prevented from starting by holding the throttle wide open while cranking. Technician B says that an engine may be disabled by removing the fuel pump fuse or relay (if equipped). Who is correct?
Answer:
Technician B
Explanation:
An engine can be disabled by removing the fuel pump fuse or relay if equipped. Therefore, Technician B is correct.
What can make an engine stop working?Engines generally stop suddenly if they suffer from a lack of fuel or sparks. An engine that can stop dead without prior warning and has probably had an instant ignition failure although when it locks solid it's more probably to have seized.
There are two ways to stop a diesel engine, remove the fuel pump fuse or cut off the fuel or the air. The easy way to stop a boat engine is to cut off the air.
The most general reasons for poor engine combustion because of broken valve seals, overused piston rings, holes within cylinders, and forcing air to leak out.
Assuming it's a gasoline-powered vehicle when removing a fuse or breaker for the ignition or fuel injection, the car wouldn't start. An engine can be disabled by cutting off the fuel pump fuse or relay if equipped.

Is the following sentence true or false? A scientific law attempts to
explain an observed pattern in nature.
It takes a person 22 seconds to swim in a straight line from the south end of
a pool to the north end of the pool, a distance of 28 meters. What is the
swimmer's velocity?
Answer:
1.27 m/s.
Explanation:
The following data were obtained from the question:
Displacement (D) = 28 m
Time (t) = 22 secs
Velocity (v) =?
Velocity is simply defined as the rate of change of displacement of an object with time. It can be represented mathematically as:
Velocity (v) = Displacement (D) /Time (t)
v = D/t
With the above formula, we can obtain the swimmer's velocity as follow:
Displacement (D) = 28 m
Time (t) = 22 secs
Velocity (v) =?
v = D/t
v = 28/22
v = 1.27 m/s
Therefore, the swimmer's velocity is 1.27 m/s.
Answer:
1.3 m/s north
Explanation:
A satellite’s original velocity is 10,000 m/s. After 60 seconds it s going 5,000 m/s. What is the acceleration? Remember acceleration = (final speed – initial speed) ÷ time .
(p.s i think this is physics? i don't know i just know its science so if anyone can help with this it would be greatly appreciated)
Explanation:
Given that,
Orginal speed, u = 10,000 m/s
Final speed, v = 5,000 m/s
Time, t = 60 s
To find,
Acceleration of the satellite.
The acceleration of an object is equal to the change in its speed divided by time. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{5000-10000}{60}\\\\a=-83.34\ m/s^2[/tex]
So, the acceleration of the satellite is [tex]83.34\ m/s^2[/tex] and it is deaccelerating.

Question 8
Four materials are put into small containers. These materials
are then moved from the small containers into larger
containers. Which material will spread out to completely fill
a larger container?
O air
oice
O sand
water
Answer:
Air
Explanation:
Matter exists in three states namely; solid, liquid and gas. These three states contain molecules/particles that behave differently from one another. The particles of gas are scattered in such a way that they move randomly in a fast motion. This causes the ability of gas particles to diffuse in an open space i.e. spread quickly
In the options of materials given in this question, AIR represents a gaseous substance, hence, it is made up of particles that move rapidly in a random manner. This will cause it to spread out (diffuse) to completely fill a larger container it is placed in.

An object moves at a constant speed of 6 m/s. This means that the object:
Answer:
The object moves 6 m in every second.
Explanation:
When we say something is constant, we simply means that it does not change with time i.e it the same through out irrespective of time.
Now, let us answer the question given above.
An object moving at a constant speed of 6 m/s. Has the following characteristics:
1. The object moves 6 m in every second.
2. The object is not accelerating since it has a constant speed. Therefore, the acceleration of the object is zero.
3. The object is moving as it covers a distance of 6 m in every second.
4. The speed remains the same since the speed of object is constant.
Thus, the right answer to question is: The object moves 6 m in every second.
An object begins with a speed of 20 meters per second and slows down to a speed of 10 meters per second over a time of 5 seconds. Calculate the average speed of the object during these 5 seconds.
can someone tell me how to do this please?
Answer:
V = 6 m/s
Explanation:
Given that,
Initial speed of an object is 20 m/s
Final speed of an object is 10 m/s
Time, t = 5 s
We need to find the average speed of the object during these 5 seconds. Let it is equal to V. Here, time is same. The average speed is given by :
[tex]V=\dfrac{x+y}{2}\\\\\text{Putting values}\\\\V=\dfrac{20+10}{5}\\\\V=6\ m/s[/tex]
So, the average speed of the object is 6 m/s.

NEED HELP ASAP Carlos is analyzing the results of a recent scientific study about gravity. Scientists recorded that the experimental value of gravity was 10.24 m/s² and the general accepted value of gravity is 9.81 m/s². Calculate the percent error of the experimental versus accepted values of gravity. 5.01% 4.38% 2.66% 9.27%
Answer:
4.38 %
Explanation:
Given that,
The experimental value of gravity is 10.24 m/s²
The general accepted value of gravity is 9.81 m/s²
We need to find the percent error of the experimental versus accepted values of gravity.
The formula used to find the percentage error is given by :
[tex]\%=\dfrac{|\text{original value-calculated value}|}{\text{original value}}[/tex]
Putting all the values:
[tex]\%g=\dfrac{|9.81-10.24|}{9.81}\times 100\\\\\%g=4.38 \%[/tex]
So, the percentage error is 4.38 %.
