answer:

the electromagnetic force

explanation:

the electromagnetic force of attraction between negative electrons and positive protons in the nucleus keeps electrons in the area surrounding the nucleus
the electromagnetic force of repulsion between positive protons in the nucleus is overcome by the strong nuclear force between protons and neutrons

Two gliders collide on an air track moving in from opposite directions, and they bounce back. The masses of the gliders are 0.20

timurjin [86]

Answer:

so initial momentum is 0.22kgm/s

Explanation:

m1=0.20kg

m2=0.30kg

initial velocity of m1=u1=0.50m/s

initial velocity of m2=u2=0.40m/s

total momentum of the system before collision

Pi=m1u1+m2u2

Pi=0.20kg×0.50m/s+0.30kg×0.40m/s

Pi=0.1kgm/s+0.12kgm/s

Pi=0.22kgm/s

The fastest recorded pitch in Major League Baseball was thrown by Nolan Ryan in 1974. If this pitch were thrown horizontally, th

8_murik_8 [283]

Answer:

45.06053 m/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

g = Acceleration due to gravity = 9.81 m/s²

a = Acceleration

$s=ut+\frac{1}{2}at^2\\\Rightarrow 0.809=0t+\frac{1}{2}\times 9.81\times t^2\\\Rightarrow t=\sqrt{\frac{0.809\times 2}{9.81}}\\\Rightarrow t=0.406\ s$

Time taken by the ball in the horizontal plane

Time = Distance / Speed

$t=\frac{18.3}{u}$

$s=\frac{1}{2}gt^2\\\Rightarrow 18.3=\frac{1}{2}\times 9.81\times \left(\frac{18.3}{u}\right)^2\\\Rightarrow u=\sqrt{\frac{1}{2}\times 9.81\times \frac{18.3^2}{0.809}}\\\Rightarrow u=45.06053\ m/s$

The Speed of the ball was 45.06053 m/s

At one instant of time, a car and a truck are traveling side by side in adjacent lanes of a highway. The car has a greater veloc

Helen [10]

Answer:

Explanation:

Acceleration is change in velocityΔv in respect to timeΔt

so if the velocity of the car is greater than the truck it does not mean that the car acceleration is greater than the truck.

Sometimes with constant velocity it means no accelaration ,but the truck may have accelaration

so, higher velocity of the car does not mean higher acceleration
