Answer: Object B is positively charged and Object C is negatively charged.

Explanation: According to Coulomb's Law, like charges repel and unlike charges attract each other.

This means that positive charge will repel positive charge and will attract negative charge.

We are given three objects , in which object A is positively charged which repels object B and attracts object C.

From the above information, we say that Object B has positive charge on it and Object C has negative charge on it.

Suppose you take two non-zero displacements represented by vectors A & B.The magnitude of A is 5 m and the magnitude of B is
olga55 [171]

Answer:

a. When the total displacement is -(A + B)

b. A + B = 1 m or -(A + B) = -11 m

c. 0 m

Explanation:

a. Under what circumstances can you end up back at your starting point?

If we have the displacement A and displacement B. The total displacement is A + B. We would end up at the starting point if we take a displacement -(A + B) from point B

b. What is the magnitude of the largest displacement you can end up from the starting point?

The maximum displacement we can obtain is when A and B are in the same direction. So A + B = 5 m + 6 m = 11 m or -A - B = -(A + B) = -11 m.

c. When A and B are perpendicular, what is the component of B in the direction of A?

Since A is perpendicular to B, the angle between A and B is 90°

So the component of B in A,s direction is Bcos90° = B × 0 = 0 m

A planet has two small satellites in circular orbits around the planet. The first satellite has a period 18.0 hours and an orbit
sasho [114]

Answer:

Time period of second satellite will be 50.904 hour

Explanation:

We have given time period of first satellite T_1=18hour

Orbital radius of first satellite a_1=2\times 10^7m

Orbital radius of second satellite a_2=4\times 10^7m

We have to find the time period of second satellite.

Time period of satellite is equal to T=2\pi \sqrt{\frac{a^3}{G(M_1+M_2)}}

From the relation we can see that T\propto a^{\frac{3}{2}}

\frac{T_1}{T_2}=\frac{a_1^\frac{3}{2}}{a_2^\frac{3}{2}}

\frac{18}{T_2}=\frac{(2\times 10^7)^\frac{3}{2}}{(4\times 10^7)^\frac{3}{2}}

\frac{18}{T_2}=(\frac{1}{2})^\frac{3}{2}

T_2=50.904hour

Time period of second satellite will be 50.904 hour

A force of 6N is exerted on a cart that is carrying a rock and produces an acceleration of 2 m/s2. If the cart has a mass of 1 k
vaieri [72.5K]
If you use the equation F=ma and re-arrange it to get m = F/a, you'll get the total mass. Then you have to subtract the mass of the cart from the total mass to get the mass of the rock. 

Thus, m = 6N over 2m/s^2. The total mass will then be 3kg. Subtracting 1kg from the total mass will then yield you 2kg, which is the mass of the rock. Hope this helps.
