Answer:

They accelerate.

Explanation:

whether an object is ar rest or in motion, when external, unbalanced forces act on it, the object accelerates, as stated in Newton's second law:

$F=ma$

where F is the net force acting on the object, m is its mass, and a its acceleration. Therefore, if there are unbalanced forces acting on the object, the object will accelerate. This means that an object at rest will start moving (in the direction of the net force), while an object already in motion will increase (or decrease, depending on the direction of the force) its velocity.

choli [55]

<h3 /><h3>Answers :</h3><h3 />

F = m×a

60 N = 30 kg × a

30 × a = 60

a = 60/30

a = 2 m/s²

<em>The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. </em>

Explanation:

If the net force increases while the mass of the object remains the same, the amount of acceleration also increases.

However, when the mass of the object increases while the net force remains the same, the amount of acceleration decreases.

A light bulb radiates 110 nW of single-frequency sinusoidal electromagnetic waves uniformly in all directions. Calculate the ave

krek1111 [17]

Answer:

The intensity of the light from the bulb would be

3.501 x $10^{-6}$ W/ $m^{2}$

Explanation:

Given

The Power = 110 n W = 110 x $10^{-9}$ W

the distance r = 50 mm = 50 /1000 = 0.05 m

The intensity can be obtained with the relationship below;

I = Power/area ......1

The area of the sphere would be used in this case since the bulb is spherical; A=4π $r^{2}$

Putting it into equation 1, we have;

I = P/ 4π $r^{2}$

I = 110 x $10^{-9}$ / 4 x π x $0.05^{2}$

I = 3.501 x $10^{-6}$ W/ $m^{2}$

Therefore the intensity of the light from the bulb would be

3.501 x $10^{-6}$ W/ $m^{2}$

Suppose students experiment with the tube and a variety of darts. Some darts have higher masses than others but are the same aer

san4es73 [151]

Answer:

The dart with the small mass will travel the farthest distance.

Explanation:

Acceleration is proportional to force times mass, and inertia is proportional to mass. Inertia is the reluctance of a moving body to stop, and a stationary body to start moving (inertia increses with mass). Assuming they both have the same aerodynamic design, and that they are both launched with the same force applied for the same time duration, the dart with less small mass will accelerate faster than the big mass dart. From this we can see that the small dart will have covered a longer distance before the effect of the force stops, when compared to the more massive dart.
