Answer:
Thermopile is an electronic device that converts thermal energy into electrical energy.
A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

Answer:
The velocity of the hay bale is - 0.5 ft/s and the acceleration is 
Solution:
As per the question:
Constant velocity of the horse in the horizontal, 
Distance of the horse on the horizontal axis, x = 10 ft
Vertical distance, y = 20 ft
Now,
Apply Pythagoras theorem to find the length:


Now, 
 (1)
                            (1)
Differentiating equation (1) w.r.t 't':


where
 = Rate of change of displacement along the horizontal
 = Rate of change of displacement along the horizontal
 = Rate of change of displacement along the vertical
 = Rate of change of displacement along the vertical
 = velocity along the x-axis.
 = velocity along the x-axis.
 = velocity along the y-axis
 = velocity along the y-axis



Acceleration of the hay bale is given by the kinematic equation:





 
        
             
        
        
        
To calculate the specific heat capacity of an object or substance, we can use the formula
c = E / m△T
Where 
c as the specific heat capacity, 
E as the energy applied (assume no heat loss to surroundings), 
m as mass and 
△T as the energy change.
Now just substitute the numbers given into the equation.
c = 2000 / 2 x 5
c = 2000/ 10
c = 200
Therefore we can conclude that the specific heat capacity of the block is 200 Jkg^-1°C^-1
