Answers
The strength of the electric field will be 215760 NC⁻¹. The concept of the electric field strength is used in the problem.
What is electric file strength?The electric field strength is defined as the ratio of electric force and charge. Its unit is NC⁻¹.
The given data in the problem is;
E is the Electric Field Strength
k is the Colomb's constant = 8.99 x 10⁹ N.m²/C²
q is the magnitude of charge = 6 μC = 6 x 10⁻⁶ C

What is an electric generator?An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
When strong magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.
Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.

Answers
Answer:
The mass=0.169
The height=57.8
The power=1.63 watts
Explanation:
The formula for mass is 2KE/v^2
v=34×34 KE=98 therefore 2*98/34^2=0.169
The formula for height is v^2/2g
v=34*34 therefore 34^2/2*10=57.8
The formula for power is work/time
in which the work is the kinetic energy =98
and time 1*60secs =60 therefore 98/60=1.63watts

of vaporisation of water is 2.26 MJ/kg (2,260,000 J/kg).
Answers
Latent heat can not be detected by a thermometer. The mass of water lost is 0.25 g.
What is latent heat?The latent heat is the heat that can not be detected by a thermometer but it acts to break the intermolecular bonds in a substance.
Now we know that;
Heat added = 565 * 10^3 J
Heat of vaporization of water = 2,260,000 J/kg
H = mL
m = H/L

A rod of length 2d0 and mass 2m0 is at rest on a flat, horizontal surface. One end of the rod is connected to a pivot that the rod will rotate around if acted upon by a net torque. A sphere of mass m0 is launched horizontally toward the free end of the rod with velocity v0, as shown in the figure. After the sphere collides with the rod, the sphere sticks to the rod and both objects rotate around the pivot with a common angular velocity. Which of the following predictions is correct about angular momentum and rotational kinetic energy of the sphere-rod system immediately before the collision and immediately after the collision?.
Answers
The angular momentum immediately before and after the collision is equal. The rotational kinetic energy before the collision is greater than the rotational kinetic energy after the collision.
What are rotational kinetic energy and angular momentum?When a body is rotating in a plane about a center, the energy possessed by the body is known as rotational kinetic energy.
Angular momentum is the momentum of a body having circular motion.
According to the law of conservation of angular momentum, the momentum remains conserved before and after the collision.
In the given sphere rod system, after the sphere (m0) sticks to the rod(2m0), the mass increases to 3m0 due to which the moment of inertia is increased but the speed is decreased.
Rotational Kinetic Energy =[tex]\frac{1}{2}[/tex]Iω²
Thus, the angular momentum immediately before and after the collision is equal. The rotational kinetic energy before the collision is greater than the rotational kinetic energy after the collision.

After the right string is cut, the meterstick swings down to where it is vertical for an instant before it swings back up in the other direction. What is the angular speed when the meterstick is vertical?.
Answers
The Angular Speed of the Meterstick after it becomes vertical is given as:
= 5.800 rad/s. This is computed using the formula for conservation of energy.
What is Angular Speed?
Angular Speed is defined as the measure of how quick or fast the central angle of a body that is rotational is changing in relation to time. Please see the attached for the full question.
What is the solution for the Angular Speed of the phenomena described?Recall that the formula for conservation of energy is given as:
(1/2)(Iω²) = mg(L/4) where
L= Lenght and
m = Mass. Please refer to the attached questions.
Factoring the moment of inertia about the pivot, we solve for the angular speed using the following formula:
ω = [tex]\sqrt{(mgL)/2I}[/tex]
= [tex]\sqrt{(6g)/7L}[/tex]
Hence, the angular speed is:
