I think the North Pole
If I understand this correctly
0.4823 m/s
The initial velocity u1 of the ball=0
From the law of conservation of linear momentum.
m1u1+m2u2=m1v1+m2v2
(160×0)+(170×u1)=(160×0.3)+(170×0.2)
u1=0.4823m/s
Answer:
Explanation:
Gauss' Law should be applied to find the E-field 3.9 cm from the surface of the sphere.
In order to apply Gauss' Law, an imaginary spherical shell (Gaussian surface) should be placed around the original sphere. The exact position of the shell must be 3.9 cm from the surface of the original sphere.
Gauss' Law states that
Here, the integral in the left-hand side is equal to the area of the imaginary surface. After all, the reason behind choosing the imaginary surface a spherical shell is to avoid this integral. The enclosed charge in the right-hand side is equal to the charge of the sphere, -84.0 nC. The radius of the imaginary surface must be 5 + 3.9 = 8.9 cm.
So,
Answer:
Matter
Explanation:
Any type of material is a matter. It can be anything that occupies space and have mass. It is a composition of atoms which in term is made up of electrons, protons and neutrons. All particles in our universe is matter because everything has some mass and it occupies space.
Well! see the car experiences 300 N force to the right from the engine.
It also experiences 150N force to left due to friction and air resistance
Now, we know it is the net force which will decide the car will move in which direction
We have net force=300-150=150N
which is towards right
So that means car will accelerate in right direction.
Hope it helps!!
