C would be your answer because we can tell by using the equation for finding force so taking m*a lets pretend I weighed 10 kg on earth and earth's acceleration is roughly 10 m/s^2 so well use that, that means I would have a force on earth of 100N and if the acceleration is increased 2.5 times I would then have a force of 250N on Jupiter which roughly translates to weight of 25 kg on earth making C the answer

How do force affect the acceleration of a body?<br><br>​
Arada [10]

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

The current through an inductor of inductance L is given by I(t) = Imax sin(ωt).
sammy [17]

Answer:

(a) emf_L=-LI_{max}\omega cos(\omega t)

(b) neither increasing or decreasing

(c) opposite to the flow of charge carriers

Explanation:

The current through an inductor of inductance L is given by:

I(t)=I_{max}sin(\omega t)   (1)

(a) The induced emf is given by the following formula

emf_L=-L\frac{dI}{dt}    (2)

You derivative the expression (1) in the expression (2):

emf_L=-L\frac{d}{dt}(I_{max}sin(\omega t))\\\\emf_L=-LI_{max}\omega cos(\omega t)

(b) At t=0 the current is zero

(c) At t = 0 the emf is:

emf_L=-\omega LI_{max}

w, L and Imax have positive values, then the emf is negative. Hence, the induced emf is opposite to the flow of the charge carriers.

(d) read the text carefully

Which of the following requires the expenditure of more​ work? ​(a) Lifting a 100 newton​ [N] weight a height of 3 meters​ [m].
umka21 [38]

Answer:

More work is done in moving a sofa than lifting a 100 N weight.

Explanation:

When a force is applied on an object and the object changes its position, then there is some work has been done on the object. Its S.I. unit is joule(J). Thus,

Work done, W = F x d       .....(1)

Here F is force applied on the object and d is displacement.

(a) In this case, force is equal to 100 N and displacement is equal to 3 m.

Substitute the values of F and d in the equation (1). Hence,

W₁ = 100 x 3 = 300 J

(b) In this case, force is equal to 60 pounds-force and displacement is equal to 30 feet. First we have to convert force and displacement in units newton and meter respectively.

As,

1 pound-force = 4.45 N

F = 60 pounds-force = 60 x 4.45 N = 267 N

1 foot = 0.3048 m

d = 30 feet = 30 x 0.3048 m = 9.144 m

Substitute these values in equation (1).

W₂ = 267 x 9.144 = 2441.4 N

Since, W₂ is greater than W₁. Hence, more work is done in moving a sofa than lifting a weight.

Which statement best describes the motion of the dots?
Ann [662]

Provided the dots represent time-lapse snapshots of an object's motion from left to right, then

(a) The underlying object is slowing down because the distance between adjacent snapshots (dots) decreases with time

(the answer is intentionally reworded to avoid sounding nonsensical)
