Work = force*displacement

displacement = (initial velocity)*(time) + (1/2)*(acceleration)*(time)^2

displacement = 0(5) + (1/2)(0.2)(5)^2

displacement = 2.5 m

Since force*displacement = work:

50(2.5) = 125 J

Which statement BEST explains why the specific heat of water is higher than the specific heat of most other substances?
solniwko [45]
Due to its polarity and hydrogen bonding water can absorb heat without a significant temperature change.. The high specific heat of water helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual instead of sudden, especially near the oceans.

to measure the static friction coefficient between a block and a vertical wall, a spring is attached to the block, is pushed on
Stolb23 [73]

Answer:

μ = mg/kx

Explanation:

Since the bock does not slip, the frictional force equals the weight of the block. So, F = mg. Now, the frictional force, F = μN where μ = coefficient of static friction and N = Normal force.

Now, the normal force equals the spring force F' = kx where k = spring constant and x = compression of spring.

N = F' = kx

So, F = μN = μkx

μkx = mg

So, μ = mg/kx

When objects are heated they tend to expand because
densk [106]
Hello!
===
When objects are heated, their molecules tend to vibrate fast. As they vibrate, the space between each atom increases. This keeps on happening, and the object expands until it has cooled down.

Hope this helps! :)

a certain car travels 20 km east then turns south for 13 km finally the car turns east again for 6 km
aliya0001 [1]

a^2+b^2=c^2

20km^2+13km^2=c^2

400km^2+169km^2=c^2
