according to Newton's 1st law, in what direction Will an object continue to move if no other outside force acts upon it​
asambeis [7]

Answer: <em>An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.</em>

Explanation: meaning, an object will continue in its same direction until stopped or acted upon by another force.

Pluto’s diameter is approximately 2370 km, and the diameter of its satellite Charon is 1250 km. Although the distance varies, th
MissTica

Answer:

r_{cm} = 2520.5 km

Explanation:

As we know that mass is the product of volume and density

so we will have

M = \rho V

here we have

M = \rho(\frac{4}{3}\pi r^3)

so we will have

\frac{M_p}{M_c} = (\frac{r_p}{r_c})^3

so we will have

\frac{M_p}{M_c} = (\frac{2370}{1250})^3

M_p = 6.81 M_c

now let the position of Pluto is at origin so we have

r_{cm} = \frac{M_p (0) + M_c(19700)}{M_p + M_c}

r_{cm} = \frac{19700}{\frac{M_p}{M_c} + 1}

r_{cm} = \frac{19700}{6.81 + 1}

r_{cm} = 2520.5 km

Jemima is running with a velocity of 5m/s. She has a mass of 65kg, what is her kinetic energy?
puteri [66]

Jemima is running with a velocity of 5m/s. She has a mass of 65kg, what is her kinetic energy would be 812.5 Joules.

<h3>What is mechanical energy?</h3>

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.

As given in the problem we have to calculate the Kinetic energy of the Jemima,

Kinetic energy = 1/2 ×mass×velocity²

                        =0.5×65×5²

                        =812.5 Joules

Thus, the kinetic energy of the Jemima would be 812.5 Joules.

A rolling ball will eventually come to a stop. Why does this happen?
Digiron [165]

Answer:

(D) friction from the ground changes the ball's

kinetic energy into heat

Explanation:

When a ball is roll on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion,that is when two surfaces come in contact with each other, the surface of one tends to oppose the motion of the other. A rolling ball stops because of friction.

A particular motor can provide a maximum torque of 110 n • m. assuming that all of this torque is used to accelerate a solid, un
hjlf

Using the rotational equivalent of force:

Which is T = I*Alpha

Where: T is torque, I is the moment of inertia and Alpha is the angular acceleration. 

This is for the flywheel: J = 1/2mr^2 = 5*3^2 = 45 kgm^2 


From the equation: 


T = J*dω/dt 


we get: 


Δt = J*Δω/T = 45*8.13/110.0 = 3.326 sec
