Answer:

9 Nm

Explanation:

The formula for torque is;

τ = lever arm * force applied

τ = 30/100 * 30

τ = 9 Nm

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.00 m/s at an angle of 20.0
Leya [2.2K]

Explanation :

When a ball is tossed from an upper storey window off a building, the height of the object as a function of time is given by :

h(t)=ut+\dfrac{1}{2}at^2

Here, u = 8 m/s

The ball strikes at an angle of 20 degrees below the horizontal. We need to find the time taken by the ball to reach a point 10 meters below the level of launching such that, h (t) = 10 m and a = g = 9.8

10=ucos(20)t+\dfrac{1}{2}\times 9.8\times (t)^2

10=0.93\times 8t+4.9t^2

10=7.51t+4.9t^2

After solving the above equation, t = 0.855 seconds

So, the ball will take 0.855 seconds to reach a point 10 m below the level of launching. Hence, this is the required solution.

How is the voltage V across the resistor related to the current I and the resistance R of the resistor? (Use I for current and R
VladimirAG [237]

Answer:

This relationship is explained by Ohm's law

Explanation:

Ohm's law states that the current flowing through a circuit or a resistor is directly proportional to the voltage across the resistor and inversely proportional to the resistance. Where current is i, voltage is v and resistance is r, Ohm's law can be represented mathematically as

V= IR

The treatment group in an experiment is also called the control group. Please select the best answer from the choices provided
JulsSmile [24]

The correct answer is:

false

The explanation:

It is not called a control group as the control group is a group of subjects closely resembling the treatment group in many demographic variables but not receiving the active medication or factor under study and thereby serving as a comparison group when treatment results are evaluated.

Part 3 of 3
Aneli [31]

Answer:

1 m/s

(i think, *nervous sweat*)

Explanation:

We can tell this by looking at the graph. When t = 8, we will look at the time. We see that when the x (time) is 8, the velocity is 1 m/s.
