Answer:
The force will be 54.0 units
Explanation:
The magnitude of the electrostatic force between two charged objects is given by Coulomb's Law:
where
k is Coulomb's constant
q1, q2 are the magnitude of the two charges
r is the separation between the two charges
From the equation, we see that the magnitude of the force is directly proportional to the charge of object 2:
In this problem, the initial force between the two objects is
F = 18.0 N
And so, when the charge on object 2 is tripled,
The new electrostatic force will be
So, the force will also triple: since the original force was 18.0 units, the new force will be
Answer:
the force is perpendicular to the speed, it is a type of force that changes the direction of the speed, as in the uniform circular motion te, but does not change its modulus.
Explanation:
The magnetic force is given by the expression
F = q v x B
The bold are vectors, where v is the velocity and B is the magnetic field, the product is the cross product whose result is a vector perpendicular to the two vectors (v and B)
From the above, the force is perpendicular to the speed, it is a type of force that changes the direction of the speed, as in the uniform circular motion te, but does not change its modulus.
Even when the change in direction is real and is caused by a centripetal force
For there to be a change in the velocity modulus there must be a force parallel to the velocity direction, generally a force in electrical
Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. The speed of light in a medium is constant.

The gravitational force acting upon the woman is equal to <u>-588.6N</u>
Why?
To solve the problem, we need to consider that two forces are acting upon the woman, the first one is related to her weight and the second one is related to the acceleration of the elevator.
Gravitational force acting upon the woman:
Hence, we have that the gravitational force acting upon the woman is equal to -588.6N.
Have a nice day!
Answer:
38.67 N
Explanation:
v = Final velocity = 40 m/s
u = Initial velocity
m = Mass of ball = 0.145kg
s = Displacement of ball = 3 m
Equation of motion
F=ma
∴ Average force that a baseball pitcher's hand exerts on the ball is 38.67 N
