The answer to the question, "How should she draw the field lines?" is option C, <span>away from the positive charge and toward the negative charge</span>
Answer:
angle = 18.40 degree
Explanation:
given data
force = 95 N
distance = 0.50 m
torque = 15 N · m
to find out
angle between the wrench handle and the direction of the applied force
solution
we will apply here torque equation that is express as
torque = distance × force × sin(θ) ...................1
put here value we will get angle that is
15 = 0.50 × 95 × sin(θ)
sin(θ) = 0.315789
θ = 18.40 degree
Answer:
No, the ball will not clear the fence.
Solution:
Angular velocity, 
Height, h = 1.2 m
Angle, 
Distance covered by the ball, d = 110 m
Length of the fence, l = 1.2 m
Radius of the axis, R = 46 cm = 0.46 m
Now,
To calculate the linear velocity of the ball, v:

Total time taken:

The distance at which the ball falls, with a = 0 is given by:

Since, the ball has to clear a fence 1.2 m long and a t a distance 110 m away, clearly it will not be able to cross it.
Answer:
This is because of Van der Waals forces
Explanation:
The ideal gas laws do not take into account the inter molecular forces that exist between the molecules of the gas. However, Van der Waals discovery showed that some weak forces of attraction exist between the molecules of the gas and at high pressures, their presence can affect the volume of the gas, making it larger than what is predicted by the ideal gas law.
These forces of attraction between the gas molecules is called Van der Waals forces.
The primary reason that surface of the venus is so much hotter than the earth is that the venus is much nearer to the sun and receives a greater amount of solar radiation as compared to the earth.
<h3>What is a solar system?</h3>
It is a system that collection of all the planets and spatial bodies revolving around the sun because of the gravitational pull of the sun.
Our Solar System is based on a heliocentric model in which the Sun is assumed to reside at the central point of the planetary system.
Since Venus is much closer to the sun than the earth and thus receives more solar radiation, this is the main cause of why the surface of Venus is so much hotter than the earth.
