Ket [755]2 years ago
4 0

Explanation:

Take F=ma

a = F/m

For a higher, F higher or m lower

Means higher horse power for engine or lower mass for the car

Westkost [7]

The kinetic energy of the block  when it reaches the bottom is 39.2 J.

<h3>Kinetic energy of the block at the bottom</h3>

Apply the principle of conservation of energy.

K.E(bottom) = P.E(top)

P.E(top) = mgh

where;

  • m is mass of the block
  • g is acceleration due to gravity
  • h is the vertical height of fall

P.E(top) = 5 x 9.8 x 0.8

P.E(top) = K.E(bottom) = 39.2 J

What is the specific heat of an unknown substance if 2000 J of energy are required to raise the temperature of 4 grams of the su
Dmitriy789 [7]
The energy required to heat a substance is related by the formula:
Q = mCpΔT ; where Q is the energy, m is the mass of the substance, Cp is the specific heat capacity and ΔT is the change in temperature.
2000 = (4)(Cp)(5)
Cp = 100 Joules / g °C

What would happen? Why?
koban [17]
Lightning rods provide low resistance paths to the ground that’ll be used to conduct the enormous electrical currents when lightning strikes happen. So the system will attempt to carry the harmful electrical current away from it and safely to ground. The system will have the ability to handle enormous electrical currents associated with the lightning strikes, if they contact a material that isn’t a good conductor then the material will suffer massive heat damage. So the lightning rod system is considered the best conductor & this allows the current to flow to the ground without causing any massive heat damage.
