Answer:

Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy.

zaharov [31]

Answer:

B. 0 degrees

Explanation:

The magnetic flux through a certain area enclosed by a loop of wire immersed in a region with magnetic field is given by:

$\Phi = B A cos \theta$

where

B is the strength of the magnetic field

A is the area enclosed by the coil

$\theta$ is the angle between the direction of the magnetic field and the direction of the normal to the coil

From the equation above, we see that the magnetic flux is maximum when

$cos \theta=1$

So when the field is parallel to the normal to the coil (so, when it is perpendicular to the coil), therefore when:

$\theta=0^{\circ}$

So, the correct option is

B. 0 degrees

Not a assignment question, just wanna know if scientists know what’s beyond the edge universe

Bond [772]

No they don’t. All the pictures we see if the universe are computer generated. Well, most of them are. We don’t exactly know how the milky way looks. It’s just very good guess.

olasank [31]

Answer:

$Mass = 0.14kg$

Explanation:

Given

$Force = 6N$

$Acceleration = 43m/s^2$

Required

Determine the mass of the ball

This question will be answered using Newton's second law of motion.

Which states that

$Force = Mass * Acceleration$

Substitute values for Force and Acceleration

$6N = Mass * 43m/s^2$

Make Mass the subject

$Mass = \frac{6N}{43m/s^2}$

$Mass = 0.13953488372$

$Mass = 0.14kg$ --- (approximated)

Which car has the most kinetic energy? <br><br> (PLEASE HELP NEED ANSWER ASAP)

Hatshy [7]

Kinetic energy = 1/2 mv²

so, you will have to do it for every single one of them if you want steps.

Kinetic Energy = For A, 202500J

For B, 90000J

For C, 168750J

For D, 75000J

From the above we an say that kinetic energy is highest in option A.

In case, there are no steps needed, just by the values we are able to understand the answer as in Option A, eventhough the mass is the same, higher the velocity or speed, higher the kinetic energy
