Answer:
V = a * t = 9.8 m/s^2 * 2.3 s = 22.5 m/s velocity after 2.3 s
S = 1/2 g t^2 since initial speed is zero
S = 1/2 * 9.8 m/s^2 * 5.29 s^2 = 25.9 m
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.
Now, moving the Moon closer to the Earth will increase the gravitational exertion of the satellite onto our planet. If the satellite were slightly closer, the tidal bulge would grow. Low tideswould be lower and high tideswould be higher and any low lying coastline would be flooded.
Answer:
<em><u>energy</u></em>
Explanation:
The heating and cooling of molecule will make <em><u>energy</u></em> change their state of matter.
