What happens if an object is in orbit and

Answer:

The object will float better.

Explanation:

If you have basic knowledge on how it works, this question is relatively easy. Let's start by reviewing something. We already know that this object (let's assume it's a spaceship of sorts) is in orbit, meaning there is already a certain amount of gravity from Earth tugging on it. We also know that space has an effect on how this moves, so the two forces "balance" each other, allowing the object to stay at orbit rather than just drifting off. Now let's see the answers to see which makes more sense.

A. The object will stop moving.

The object can't stop moving. With gravity increasing, it would be impossible for that to happen.

B. The object will fly off into space.

This could only happen if the gravity were to decrease by a decent amount.

C. The object will smash into another object.

There is no other object mentioned in the question.

D. The object will float better.

This seems most likely as gravity would be pulling on the object a bit more, but probably not enough to bring it back to the ground. It might drop a bit lower into the exosphere.

I hope I was right and I hope this helps!

A 50.0 kg object rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.300 and

MariettaO [177]

Answer:

$f=140\ N$

Explanation:

Given:

mass of the object on a horizontal surface, $m=50\ kg$

coefficient of static friction, $\mu_s=0.3$

coefficient of kinetic friction, $\mu_k=0.2$

horizontal force on the object, $F=140\ N$

<u>Now the value of limiting frictional force offered by the contact surface tending to have a relative motion under the effect of force:</u>

$F_s=\mu_s.N$

where:

$N=$ normal force of reaction acting on the body= weight of the body

$F_s=0.3\times (50\times 9.8)$

$F_s=147\ N$

As we know that the frictional force acting on the body is always in the opposite direction:

So, the frictional force will not be at its maximum and will be equal in magnitude to the applied external force and hence the body will not move.

so, the frictional force will be:

$f=140\ N$

A charge of 1.5 µC is placed on the plates of a parallel plate capacitor. The change in voltage across the plates is 36 V. How m

belka [17]

Answer:

Energy stored in the capacitor is $U=2.7\times 10^{-5}\ J$

Explanation:

It is given that,

Charge, $q=1.5\ \mu C=1.5\times 10^{-6}\ C$

Potential difference, V = 36 V

We need to find the potential energy is stored in the capacitor. The stored potential energy is given by :

$U=\dfrac{1}{2}q\times V$

$U=\dfrac{1}{2}\times 1.5\times 10^{-6}\times 36$

U = 0.000027 J

$U=2.7\times 10^{-5}\ J$

So, the potential energy is stored in the capacitor is $U=2.7\times 10^{-5}\ J$ . Hence, this is the required solution.

Do heavier objects fall more slowly than lighter objects?

aksik [14]

Think of it like this, gravity has to pull harder on the heavier object to make them fall at the same rate , but doesn't have to pull as hard for the lighter object , thus is why sometimes heavier objects fall faster then lighter ones

Answer:

TDR means Timeout Detection and Recovery.

Explanation:

TDR is a feature of the Windows operating system which detects response problems from a graphics card, and recovers to a functional desktop by resetting the card. If the operating system does not receive a response from a graphics card within a certain amount of time (default is 2 seconds), the operating system resets the graphics card.
