The force acting on a moving charge is known as the magnetic force. The force acting on the charge will be 3.75 N.
What is the force exerted on the charge?Magnetic fields only exert a force on a moving electric charge. A moving charge generates a magnetic field. With an increase in charge and magnetic field strength, this force rises.
when charges have higher velocities, the force is stronger. However, the magnetic force is always perpendicular to the velocity.
Mathematically the force exerted on the charge will be
F=qvBsinα
F= force acting on the charge= 7.5 ×10⁻²
v = velocity of charge=2.5 ×10⁴
q = charge=?
B= 8.1 ×10⁻²
F=qvBsinα
[tex]\rm{q= \frac{F}{vBsina}}[/tex]
[tex]\rm{q= \frac{7.5\times 10^-2}{2.4\times 10^-2 \times 8.1\times 10^-2 sin25^0}}[/tex]
q = [tex]8.8 \times 10^ {-5}\rm C[/tex]
Hence the value of the charge will be [tex]8.8 \times 10^ {-5}\rm C[/tex].

to a stop
Inertia is the tendency of an object to stay in the current state. Hence, the stationary car has a tendency to continue in the state of rest. Quick starts up will make it move backward or if stop quickly while moving, it goes forward.
What is inertia ?According to Newton's first law of motion, an objects tends to continue in its state of motion or rest until an external force acting on it. This tendency of the objects is called inertia.
The impacts of inertia can be well explained based on on real life examples. If we might had the experience of moving to front in a vehicle which suddenly breakes. It is the tendency of the vehicle to stay in motion.
Similarly the car when started from rest initially tends to stay at rest and that's why we feel it moves back ward. Similarly the car will move forward when it is suddenly stops.

Two large parallel metal plates are 6.0 cm apart. The magnitude of the electric field between them is 600 N/C. What work is done when one electron is moved from the positive to the negative plate? Note: the charge of an electron is 1.6 x 10-19 C.
3.36 x 10-20 J
4.98 x 10-17 J
1.6 x 10-19 J
5.76 x 10-18 J
Answer:
Approximately [tex]5.76 \times 10^{-18}\; {\rm J}[/tex] (by the external force that moved the electron.)
Explanation:
Let [tex]q[/tex] denote the magnitude of a charge in an electric field of magnitude [tex]E[/tex]. The magnitude of the electrostatic force on that charge would be:
[tex]F = q\, E[/tex].
In the electric field in this question, the magnitude of the electric force on the electron would be:
[tex]\begin{aligned}F &= q\, E \\ &= 1.6 \times 10^{-19}\; {\rm C} \times 600\; {\rm N \cdot C^{-1}} \\ &= 9.6 \times 10^{-17} \; {\rm N}\end{aligned}[/tex].
Moving the electron to the other plate would thus require an external force of [tex]9.6 \times 10^{-17}\; {\rm N}[/tex].
This force needs to be exerted over a distance of [tex]6.0\; {\rm cm}[/tex] ([tex]6.0 \times 10^{-2}\; {\rm m}[/tex].) The direction of the motion is the same direction as that of the external force. Thus, the work that needs to be done would be:
[tex]\begin{aligned}W &= F\, s \\ &\approx 9.6 \times 10^{-17}\; {\rm N} \times 6.0 \times 10^{-2}\; {\rm m} \\ &\approx 5.76 \times 10^{-18}\; {\rm J}\end{aligned}[/tex].

Two carts collide and bounce apart. Cart 1 had a momentum of –6 kg • m/s before the collision. Cart 2 had a momentum of 10 kg • m/s before the collision.
What is the total momentum of the carts after the collision?
–16 kg • m/s
–10 kg • m/s
4 kg • m/s
10 kg • m/s
Answer:
4 kg m/s
Explanation:
When finding momentum after a collision, you can just add the momentums together, this would be 10 kgm/s -6 kgm/s to get 4 kgm/s
The total momentum of the carts after the collision is 4 kgm/s.
What is momentum?The momentum of an object is the product of mass and velocity of the object.
P = mv
Total momentum of the cartsThe total momentum of the carts is calculated as follows;
P = P₁ + P₂
P = -6 + 10
P = 4 kgm/s
Thus, the total momentum of the carts after the collision is 4 kgm/s.

Does a magnetic field require any tr ansfer or movement of mass or particles?
Answer:
The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. In a magnetic field, a moving charge experiences a force that is perpendicular to both its own velocity and the magnetic field. The magnetic field of a permanent magnet attracts or repels other magnets, as well as ferromagnetic elements like iron. Furthermore, a varying magnetic field exerts a force on a variety of non-magnetic materials by changing the mobility of their outer atomic electrons.

A car accelerates at a rate of 3.0
m/s2 after stopping at a red light. If
the mass of the car is 3000 kg, what
force does its engine exert?
The force of the car's engine exerts is 6000 N.
To find the force, the given values are,
acceleration, a = 3 m/s².
mass = 3000 kg
What is Newton's second law?Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. According to Newton's second law of motion, the acceleration of a body is directly proportional to the force acting on the body and inversely proportional to its mass. The formula for the Newton's second law isAcceleration, a = Force F/ Mass m
From which we get the formula
Force F = Mass m × Acceleration a
Where, mass is kg and acceleration is m/s².
The unit of force is kgm/s² or N.where kg is kilogram-meter per second square or Newton.
Substituting the Equation in:
F = ma
= 3000kg x 2m/s²
= 6000kgm/s²
F = 6000 N.
So, the Force of the car engine exerted is 6000 N.

Which has more momentum: a 20,000 kg cement truck traveling at 5 m/s or a 1000 kg race car traveling at 90 m/s
Hi there!
Recall the equation for momentum:
[tex]\large\boxed{p = mv}[/tex]
p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
We can calculate each object's momentum and compare.
Cement truck:
[tex]p = 20000 \cdot 5 = 100000kg\frac{m}{s}[/tex]
Race car:
[tex]p = 1000 \cdot 90 = 90000 kg\frac{m}{s}}[/tex]
Since 100,000 > 90,000, the cement truck has the greater momentum.

A dancer moves around a path like the one
shown in the figure below with a constant
speed
Which of the following best represents the
magnitude of the dancer's acceleration as a
function of time t during one trip around the
path, beginning at point P?
21
Given what we know, despite not having the figure attached to the question, we can still confirm that the magnitude for the acceleration of the dancer will be zero.
Why is the dancer's acceleration equal to zero?This has to do with how the question clarifies the speed of the dancer. Though it does not give us an exact value, we are told that the speed is constant. This is an indicator that the acceleration is zero because with any other value for acceleration the speed cannot remain constant.
Therefore, given that any value for acceleration will increase or decrease the speed of the dancer, but we are told that the dancer's speed is constant throughout the trip, we can confirm that the magnitude for the acceleration of the dancer is zero.
