Remain the same

Explanation:

If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same.

 Work done is the force applied to move a body through a distance.

Work done = F x d

where F is the applied force

            d is the distance moved

Now;

if:

    f = 2f

    d = \frac{1}{2}d

Input the parameter:

 Work done = fxd = 2f x \frac{1}{2}d  = fd

The work done will still remain the same

In order to create a charged object, you need to ________.
Brums [2.3K]
In order to create a charged object you need to transfer electrons either away or to the object by induction, conduction, or friction

Induction is without contact(like bringing a charged object to a electroscope charges the leaves at the bottom)
Conduction is with contact(like the previous answer, wore touching transfers the charge from a source to the object)
Friction(rubbing a balloon on wool)

A truck speeds up from velocity of 6m/s to 14m/s in 4 seconds. what is the trucks acceleration?
Tanzania [10]

To calculate the acceleration of the truck, we use the equation of motion

v = u + at

Here, v is final velocity of the truck, u is initial velocity of truck, a is acceleration of the truck and t is time taken.

Given,  u = 6 m/s, v = 14 m/s and t = 4 s.

Substituting these values in above equation, we get

14 \ m/s = 6 \ m/s + a \times 4 \ s \\\\  a = \frac{14 \ m/s - 6 \ m/s}{ 4 \ s } =  2 \ m /s^2.

Thus,  the truck acceleration is 2 \ m /s^2

you can use a torque feeler that consists of a meterstick held at the 0 cm end with a weight dangling from various positions alo
Deffense [45]

Answer:

T=7.3575\ N.m

Explanation:

Given:

length of the stick, l=100\ cm=1\ m

position of holding the stick that acts as a hinge, f=0\ cm

mass of the object, m=1\ kg

position of hanging the mass on the meter stick, x=50\ cm=0.5\ m

new position of hanging the mass, x'=75\ cm=0.75\ m

<u>Now the torque in the initial position:</u>

T=mg.x

where:

g= acceleration due to gravity

T=1\times 9.81\times 0.5

T=4.905\ N.m

Now when the mass is at the new position:

T=mg.x'

T=1\times 9.81\times 0.75

T=7.3575\ N.m
