Answer:
3.0 x 10¹ Nm
Explanation:
Torque = F x r
Where F is force applied and r is perpendicular distance from pivot point . r
is also called lever arm
Here F = 15 N and r = 2.0 m
Torque
= 15 N X 2.0 m
= 3.0 10¹ Nm.
Answer:
m g = G * m * M / R^2 force of attraction
g = G * M / R^2
g = 6.67E-11 * 5.96E24 / (6.37E6)^2
g = 6.67 * 5.96 / 6.37^2 * 10^1
g = .98 * 10 = 9.8 m/s^2
Q2.
d g = G M * (-2 R^-3 dR ) = -2 G M / R^3 (very small where dR = 1)

it he answer is a trachea
Answer:
Conduction
Explanation:
Conduction. When a substance is heated, its particles gain internal energy and move more vigorously. The particles bump into nearby particles and make them vibrate more. This passes internal energy through the substance by conduction , from the hot end to the cold end.
Answer:

Explanation:
Work is the product of force and distance, so the formula is:

The work is 6.00 Joules, but
- 1 Joule (J) is equal to 1 Newton meter (N*m).
- Therefore, the work of 6.00 J is equal to 6.00 N*m
The force is 2.50 Newtons.
The known values are:
Substitute the values into the formula.

We are solving for distance, so we must isolate the variable, d. It is being multiplied by 2.50 Newtons and the inverse of multiplication is division. Divide both sides by 2.50 N.


The units of Newtons cancel out.


The force was applied to the rock over a distance of <u>2.40 meters</u> and choice <u>C</u> is correct.
