Two forces act in opposite directions on a wood block. What will happen if the forces are unbalanced?

Physics
1 answer:
worty [1.4K]2 years ago
7 0

Answer:

D

Explanation:

If two unequal forces act in opposite directions, one larger force must cancel out the smaller force,

leaving the net force to be some number in one direction.

Take for example a game of tug-of-war; there are two  OPPOSITE forces (groups of people) acting on the rope, one force is pulling with a force in the negative direction while the other force is pulling in the positive direction.

If the forces on the rope were unequal, then the stronger force (group) will pull everything in their direction.

The same will happen on two unequal forces of opposite directions acting on a wooden block. Therefore, since the resultant force will have a non-zero magnitude and direction, there will be a change in the block's motion and position.

Two atoms that are isotopes of one another must have the same number of what?
fredd [130]

Answer:

B

Explanation:

Two atoms which are isotopes of one another must have a different number of neutrons.

Isotopes are defined as atoms of the same element which have the same numbers of protons i.e. atomic number remains the same, but has different numbers of neutrons. It is observed that they have same chemical properties due to the same electronic configuration but physical properties differs.

How does the egg drop project apply to newtons 3 laws of motion
iren2701 [21]
The reason why it relates to the newtons 3 laws of motion because the first law of motion states that every object will stay at rest unless it's moved by an unbalanced force which is your hand. The second one states that <span> the velocity of an object changes when it is subjected to an external force meaning it's used by the equation that is commonly used for which is F=M*A. The way it relates to the second law because you are adding force some way or another, the mass is the egg and the acceleration is the drop of the egg while it free falls. And the last one, for a reaction there is always an equal or opposite reaction and the opposite reaction is the floor because it's going against the egg causing it to crack. If it was with the egg, it would have a soft, smooth landing.</span>

The International Space Station is orbiting at an altitude of about 370 km above the earth's surface. The mass of the earth is 5
Varvara68 [4.7K]

Answer:

T = 5516.63 seconds

Explanation:

Given that,

The International Space Station is orbiting at an altitude of about 370 km above the earth's surface.

Mass of the Earth, M=5.976 \times 10^{24}\ kg

Radius of Earth, r=6.378\times 10^6\ m

We need to find the period of the International Space Station's orbit. It is a case of Kepler's third law. Its mathematical form is given by :

T^2=\dfrac{4\pi^2}{GM}\times R^3

R = r + h

T^2=\dfrac{4\pi^2}{6.67\times 10^{-11}\times 5.976 \times 10^{24}}\times (370000+6.378\times 10^6)^3\\\\T^2=30433264.1641\ s\\\\T=5516.63\ s

So, the period of the International Space Station's orbit is 5516.63 seconds.
