Put object into cylinder and notice the volume increased. Difference of volume is the object's volume
It will take the battery 15 hours to discharge completely.
<h3>Energy stored in a battery</h3>
Energy is defined as the ability or capacity to work. The formula for calculating the energy stored in a battery is expressed as;
Energy stored=Power×Time
Energy stored = ΔV * t
where
ΔV is the change in velocity
t is the time
Substitute
Energy stored = 12.0 * 90.0
Energy stored = 1080 W.h
Total power consumed by the headlight = 2 * 36
Total power consumed by the headlight = 72Watts
Determine the time it takes to dischage
Time = Energy Stored/Power
Time = 1080/72
Time = 15hrs
Hence it will take the battery 15 hours to discharge completely.

Answer:
They both are part of electromagnetic radiation.
Radio waves have longer wavelength than visible waves.
Radio waves have lower frequency than visible waves.
Explanation:
Answer:
Part a)

Part b)

Part c)

Part d)
from t = 0 to t = 4.9 s
so the reading of the scale will be same as that of weight of the block
Then its speed will reduce to zero in next 3.2 s
from t = 4.9 to t = 8.1 s
The reading of the scale will be less than the actual mass
Explanation:
Part a)
When elevator is ascending with constant speed then we will have



So it will read same as that of the mass

Part b)
When elevator is decending with constant speed then we will have



So it will read same as that of the mass

Part c)
When elevator is ascending with constant speed 39 m/s and acceleration 10 m/s/s then we will have



Reading is given as



Part d)
Here the speed of the elevator is constant initially
from t = 0 to t = 4.9 s
so the reading of the scale will be same as that of weight of the block
Then its speed will reduce to zero in next 3.2 s
from t = 4.9 to t = 8.1 s
The reading of the scale will be less than the actual mass
Answer:
100°c = 373.15 K
100°C=212°F
Explanation:
To convert Celsius to Kelvin, we need the following equation.
°C + 273.15 = K
100°C + 273.15 = K
373.15 = K
Therefore, 100°c = 373.15 K
F = 9/5C + 32
=9/5(100)+32
= (180) + 32
= 212°
Therefore,
100°C=212°F
