Well little kids i think are trying to pull down a adult but only the adult will only move a smudge so i guess there will be no movement? this may be wrong so i don’t know sorry if u get it wrong
Answer:
The heat capacity of a sample is 37.7 J/K.
Explanation:
Given that,
Submerged temperature of tissue sample = 275 K
Mass of liquid nitrogen= 2 kg
Temperature = 70 K
Final temperature = 75 K
We need to calculate the heat
Using formula of heat
Put the value into the formula
We need to calculate the heat capacity of a sample
Using formula of heat capacity
Put the value into the formula
Hence, The heat capacity of a sample is 37.7 J/K.
Answer:
C
Explanation:
The answer is straight line motion
Centripetal acceleration is given as
here we know that
v = speed of the car
R = radius of curvature of the car
now here we can see that the acceleration of car directly depends on the square of the speed
so here if speed of the car is tripled then centripetal acceleration will be increased by square times
so here centripetal acceleration is increased by 9 times if speed is tripled
