Hahahahaha. Okay.
So basically , force is equal to mass into acceleration.
F=ma
so when F=ma , we get acceleration=6m/s/s
Force is doubled.
Mass is 1/3 times original.
2F=1/3ma
Now , we rearrange , and we get 6F=ma
So , now for 6 times the original force , we get 6 times the initial acceleration.
So new acceleration = 6*6= 36m/s/s
This happens in basketball. It is known as "jump ball".
A. 90km/h = 25 m/s
W=1/2mv^2
=1/2* 650* 25^2
= 203125(J)
b. v’= 90-50= 40km/h
= 100/9 m/s
W=1/2mv^2
=1/2*650*(100/9)^2
= 40123,45679
Answer:
An object that is thrown, kicked or otherwise launched through the air is called a projectile.
Explanation:
Answer:
Because they propagate due to presence of magnetic and electric field.
Explanation:
An Electromagnetic wave is a transversal wave conformed of an electric field perpendicular to a magnetic field.
Maxwell established that an electric field can generate a magnetic field and vice versa, which allows the propagation of the electromagnetic wave without a medium.
