Avanadium bolt gives up 1124 j of energy as its temperature drops 25 k if the bolts mass is 93 g what is its specific heat

0.483 J/(gK)

Explanation:

When a sample of a material of mass m gives off an amount of energy Q, the temperature of the material decreases by , according to the equation :

where   is the specific heat capacity of the material.

In this problem, we have:

m = 93 g is the mass of the vanadium bolt

is the amount of energy given off by the vanadium bolt

is the change in temperature of the vanadium

Solving the equation for , we find the specific heat capacity of vanadium:

the closer the planet is to the sun, the larger the gravity

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
