According to my guesses, he should have swung the pendulam bob and noted its time period. In order to observe the effect of mass, he would have repeated the experiment with varied pendulam bobs. Hope this helped!
Answer:
<h3>16,071.42J/kgK</h3>
Explanation:
The formula for expressing the quantity of heat released is expressed as;
Q = mcΔt
m is the mass of the substance = 100g - 0.1kg
c is the specific heat capacity of the substance
Δt is the change in temperature = 13 -(-15) = 28°C
Substitute and get c;
45000 = 0.1c(28)
2.8c = 45000
c = 45000/2.8
c = 16,071.42J/kgK
Hence the specific heat capacity of the substance is 16,071.42J/kgK
Answer:
F = 1024 N
Explanation:
Given that,
Mass of the cart, m = 80 kg
Radius of the loop, r = 5 m
Speed of the cart, v = 8 m/s
To find,
the force exerted on the track on the cart.
Solution,
The force exerted on the track on the cart is called centripetal force. When an object moves in a circular path it possess centripetal force. It is given by :
F = 1024 N
So, the force exerted on the track on the cart is 1024 N.
