The force can be determined using the equation F (force) = mass * acceleration. The unit of measurement, N (Newton), is equivalent to kilogram-meter/seconds2.
Thus, F= 1300 kg * 1.07 m/s2 = 1391 N.
The resultant value is 1391 N.
Let Cp represent the specific heat of the metal object.
To find this, we can set up a heat balance equation (heat lost by metal = heat gained by water):
- 19g * Cp * (22degC – 96degC) = 75g * 4.184J/g degC * (22degC - 18degC)
<span>Cp = 0.893 J/g degC</span>
Response:
(e) thermal expansion
Clarification:
The density, heat of fusion, and melting temperature of a metal are critical factors to consider when increasing its temperature from room temperature to its melting point. These will dictate the following aspects:
Density: refers to the ratio between a body's mass and the space it occupies in the universe.
Heat of fusion: The enthalpy of fusion or heat of fusion signifies the amount of energy required to cause a mole of an element at its melting point to transition from solid to liquid state, under constant pressure.
Melting temperature is defined as the thermal level at which the phase change from solid to liquid takes place under standard atmospheric pressure.
On the other hand, the dilution of metals only influences the volume they will occupy without affecting the heating process
The pickup truck accelerates to the right. The box adheres to the truck, resulting in identical acceleration to the right. Its inertia, however, opposes this acceleration, acting to the left. Therefore, for the box to stay in place, the truck must exert a force to the right. (The forces exerted by the truck and the box's inertia counterbalance each other).
