Answer:
option d)
Explanation:
The amount of heat required to convert the 1 g of ice at 0 degree C to 1 g water at 0 degree C is called latent heta of fusion.
H = m Lf
where,, h is the heat required, m is the mass and Lf is the latent heat of fusion
1140 = m x 79.7
m = 14.3 g
Here's a perfect example of a stable and unstable system.
Answer:
66.85 m
Explanation:
We are given that
Acceleration ,a=
Speed of truck, v=9.5 m/s
We have to find the distance beyond which the traffic signal will the automobile overtake the truck.
Initial speed of automobile, u=0
We know that

Using the formula

For constant speed
Acceleration, a=0
Again



Substitute the value of t

Hence, the distance beyond which the traffic signal will the automobile overtake the truck=66.85 m
Explanation:
sinces : Momentum = velocity × mass
then : 30 = 10 × m and m = 30 ÷ 10 = 3 kg
