Answer:
Its acceleration is certainly negative.
Explanation:
- When an object moving in a straight line decelerates then its velocity certainly decreases.
- Its acceleration is certainly negative.
- As we know that acceleration is the rate of change in velocity and the object is decelerating i.e. its velocity is reducing with time.
where:
are final and initial velocities of the object
are final and initial time of observation.
- Its SI unit is
Answer: 8400 J
Explanation:
The formula referenced in the question is:
Where:
is the thermal energy
is the mass of the water sample
is the specific heat capacity of water
is the variation in temperature
Solving:
This is the thermal energy released
What unit? I don’t see anything to help you answer.
Answer:
Voltage, Zero
Explanation:
If an electric circuit has 0 A of current running through it, then the ✔ voltage must be ✔ zero.
1000 litres of water can fill a tank of 1m3 capacity because water has a density of 1000kg/m3 and as 1 kg water = 1 liter ,
1000 liter of water can fill a tank of 1m3
