Answer:
option (D)
Explanation:
your distance from the plane mirror = 2.4 m
According to the property of the plane mirror, the distance between the object and the mirror is equal to the distance between the image and the mirror.
So, the distance between you and your image is two times the distance between you and mirror.
the distance between you and your image = 2 x 2.4 = 4.8 m
Answer:
It requires <u>1.9 seconds</u> to reach maximum height.
Explanation:
As per given question,
Initial velocity (U) =19 m/s
Final velocity (V) = 0 m/s
Maximum height = S
Time taken is "t"
<u>Calculating time taken to reach maximum height:</u>
We know that time taken to reach the maximum height is calculated by using the formula V = U + at
Substitute the given values in the above equation.
Final velocity is “0” as there is no velocity at the maximum height.
t = 1.9 seconds.
The time taken to reach maximum height is <u>1.9</u> seconds.
<u>Calculating maximum height</u>:
Solving the equation we will get the value of S
-361 = -20S
Negative sign cancel both the sides.
S = 18.05 m
Maximum height is 18.05 m .
Describe the path light waves take when you see your image in the mirror?
<span>light strikes your face and bounces off of it. then, light is reflected off your face and into the mirror. i is hen reflected into your eyes.</span>
Answer:
We understand that two like poles of magnet repel each other. Maglev train is based on the same concept. The train levitates above the tracks because of repulsion between one set of magnets. One set of magnets lifts the train upwards causing it to levitate or float above tracks and other set of magnets causes it to move forward. This method enables less consumption of energy as loss of energy due to friction is negligible and also, high speed can be achieved.
