Answer:

Fc = 123 Newton

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

Fnet = Fapp + Fg

Where;

Fnet is the net force.

Fapp is the applied force.

Fg is the force due to gravitation.

Given the following data;

Normal force = 25N

Mass = 10kg

To find the centripetal force;

From the net force, we have the following formula;

Fc = N + mg

Where;

Fc is the centripetal force.

N is the normal force.

mg is the the weight of the object.

Substituting into the formula, we have;

Fc = 25 + 10(9.8)

Fc = 25 + 98

Fc = 123 Newton

A ball starts from rest and undergoes uniform acceleration of 2.50m/s^2. What is the velocity of the ball 4s later?
erica [24]

Explanation:

Given:

v₀ = 0 m/s

a = 2.50 m/s²

t = 4 s

Find: v

v = at + v₀

v = (2.50 m/s²) (4 s) + 0 m/s

v = 10 m/s

A motor uses motion in a magnetic field to produce an electric current. true or false
irinina [24]

Well, that's a nice, concise description, but it applies to a
generator, not a motor.  A motor does exactly the opposite.
It uses an electric current to produce motion in a magnetic field.

Sadly, the statement is false.

gladu [14]
Here are many things that exist as liquid at "normal" Earth temperatures. I would bet that you've seen a demonstration or someone use something with liquid mercury.

What is the angle between a rigid object and the force applied to it that yields torque using the equation T=Fd?
baherus [9]
Angle between should be 90 degrees. That is the condition for the formula of Torque , T = Fd.
Actually the d is the perpendicular distance.

What is the magnitude of the electric field 17.1 cm directly above an isolated 1.83Ã10â5 C charge?
11111nata11111 [884]

Answer:

Electric field, E=5.63\times 10^{16}\ N/C

Explanation:

Given that,

Charge, q=1.83\times 10^5\ C

We need to find the magnitude of electric field 17.1 cm (0.171 m) above an isolated charge. Electric field at a point is given by :

E=\dfrac{kq}{r^2}

E=\dfrac{9\times 10^9\times 1.83\times 10^5\ C}{(0.171\ m)^2}

E=5.63\times 10^{16}\ N/C

So, the electric field is 5.63\times 10^{16}\ N/C. Hence, this is the required solution.
