How could you measure the strength of static electricity compared to the strength of an
electromagnet?

Answers

Answer 1

Answer:

Lines of Force around an Electromagnet

Explanation:

The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field

At 10°C, the gas in a cylinder has a volume of 0.250 L. The gas is allowed to expand to 0.285 L.


What must the final temperature be for the pressure to remain constant? (Hint °C + 273 = K.)


282 K


284 K


323 K


248 K

Answers

Explanation :Use the formula: P1V1T1=P2V2T2
We know that we want P1=P2 so the pressure will remain constant, so we can say that: P1V1T1=P1V2T2
Plug in the values we know: P1⋅0.250L283K=P1⋅0.285LT2
(Remember that temperature must be done in Kelvin.)
Cross multiply: T2⋅P1⋅0.250L=283K⋅P1⋅0.285L
Divide both sides by P1.
T2⋅0.250L=283K⋅0.285L
T2=283K⋅0.285L0.250L
T2=323K
(This is also 50˚C.)

Answer:

1.308104*10^-8 N (1.31*10^-8 N when rounded)

Explanation:

The mathematical formula for gravitational force is  F = G Mm /r^2  where  G  is the gravitational constant which is measured 6.674 *10^ − 11 N (m/kg) ^2.

Since both objects, M and m, have masses of 70kg and the distance r is 5 meters, then we can plug these values into the formula:

F=GMm/r^2

F=(6.674*10^-11)(70)(70)/(5^2)

F=(6.674*10^-11)(4900)/25

F=(3.27026*10^-7)/25

F=1.308104*10^-8

So the gravitational force of attraction between the two objects is 1.308104*10^-8 N.

How do we know when an object is in static or dynamic equilibrium?

Answers

Answer:

First Condition of Equilibrium

Explanation:

This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.
