Answer:
200 m
Explanation:
Both Jerry and Tom start at the end of the pipe where the cheese is. Jerry then runs into the pipe at 20 m/s while Tom chases him at 10 m/s. When Jerry reaches the other end of the pipe, where Tom's cousin is, he turns around. Eventually, he reaches Tom again, so he turns around again. This continues until both Tom and Jerry reach the end of the pipe where Tom's cousin is.
We need to find the distance traveled by Jerry. We already know Jerry's speed, so we just need to find the time. We can do that using Tom's speed and the length of the pipe.
x = vt
100 m = (10 m/s) t
t = 10 s
So both Tom and Jerry run for 10 seconds. Since Jerry runs at a speed of 20 m/s, the distance he travels is:
x = vt
x = (20 m/s) (10 s)
x = 200 m
Jerry runs a distance of 200 meters.
Answer:
Explanation:
The capacitance of a capacitor in terms of the dielectric constant, area of the plate and the distance separating the plate is given by:
Where A = Area of the plate
d = distance between the plates
dielectric constant
Case 1:
When a meta slab of thickness, a, is added between the plates of the parallel plate capacitor , the effective separation between the plates becomes d+a
Therefore the capacitance of the capacitor becomes:
.......................(1)
Case 2:
Introducing a dielectric with dielectric constant K between the plates, the capacitance of the capacitor becomes:
.........................(2)
Equating (1) and (2)
Answer:
3 m/s
Explanation:
<u>The velocity of a position-time graph is the slope of the line.</u> Slope is rise over run, or rise divided by run. The rise (how many units the line goes up) is 3 units and the run is 1 unit. 3/1 is 3, so the velocity is 3 m/s.
Answer:
Water has the ability to release a large amount of energy during the freezing process. All of this energy is released into the air, resulting in a greater movement of air particles that will increase the air temperature. This heat will prevent air temperatures from drastically falling below 0ºC.
Explanation:
The latent heat of water occurs when the water is changing its physical state. In other words, when substances are changing their physical state, the amount of heat calculated for this change is called latent heat, and as we have already said, this heat is not related to the heat exchanges between two systems, but the change of state. physicist.
When water is changing from its liquid state to a solid state, we call latent heat latent heat from fusion (this is because fusion is the name we give to when liquid water is turning to ice). In the process of freezing the page, latent heat releases a large amount of energy into the air near the water. This energy agitates the air molecules, generating heat and preventing the air from reaching temperatures below 0ºC.
Explanation:
Given that,
Initial speed of a car, u = 60 km/h = 16.67 m/s
Acceleration, a = 2m/s²
Final speed, v = 120 km/h = 33.33 m/s
We need to find the distance traveled and the time taken to make the distance.
acceleration = rate of change of velocity
let the distance be d.
Hence, the distance traveled and the time taken to make the distance is 208.25 m and 8.33 seconds respectively.
