Speed = 52/1.57576= 33 m/s
Explanation:
Distance = speed * time
Given , the distance traveled by the baseball = 52 m
Speed of sound in air = 330 m/s
Total time = 1.73333 s .
Total time for the student to hear the sound of the gong is the sum of the time take for the baseball to reach the gong and the time taken by the sound to travel back.
Distance traveled by the sound is 52 m and the speed is 330 m/s
So time taken by the sound to travel back = distance traveled / the speed
=> time = 52/330 s = 0.15757 s
Time taken by the base ball to reach the gong is the total time - the time taken by the sound
=> time taken by base ball = 1.73333 - 0.15757 = 1.57576s
Speed of the base ball to reach the gong = distance / time
Speed = 52/1.57576= 33 m/s
Answer:
Natural Sciences
Explanation:
This network would fall under the lens of Natural Sciences. This is based on what the family is currently watching. Nature documentaries focus on our Planet as well as all the wildlife in it. In these documentaries, they talk about how and why certain things in nature occur. All of this would be considered educational information on the subjects of Earth Science and Biology which are main subcategories under the lens of Natural Sciences.
That's a battery or other "power supply".
Answer:

Explanation:
The circular movement is produced by the magnetic field:

This force is a centripetal force because the electron moves in a plane perpendicular to the magnetic field. For a centripetal Force, that produces a circular orbit with a radius r:

If we solve these two equations in order to find r, with the mass and charge of a electron:

Answer:
So police car will overtake the speeder after 5.64 s
Explanation:
Initially the distance between police car and the speeder when police car is about to accelerate




now we have
now velocity of police with respect to speeder is given as

relative acceleration of police car with respect to speeder

now the time taken to cover the distance between police car and speeder is given as
