Explain our ideas about why the terrestrial planets are rocky and have less gas than the giant planets.

Physics
1 answer:
snow_lady [41]3 years ago
3 0

Answer: The terrestrial planets are mainly comprised of silicate minerals and also there is presence of some metals, which were subsequently formed in the geological time scale, after the accumulation of smaller dust particles, due to the gravitational pull, during the time of formation of the planets.

Due to the location of these terrestrial planets near to the sun, their surface temperature is high enough to hold the gases like hydrogen and helium. Thus, they have a high density but less gases compared to the outer planets.

A point charge Q is located a short distance from a point charge 3Q, and no other charges are present. If the electrical force o
weeeeeb [17]

Answer:

d) F

Explanation:

According to columb's law:

"The magnitude of electrostatic force between two charges is directly proportional to the product of magnitude of two charges and inversly proportional to separation between them."

If q₁ and q₂ are magnitude of two charges, d is distance between them and k is dielectric constant, then force F is given by

                                               

                                              F=\frac{kq_{1}q_{2}}{d^2}

According to this force exerted on point charge Q is same as that of 3Q, so force point 3Q charge experience is also F

You must exert a force of 4.5 N on a book to slide it across a table. If you do 2.7J
hoa [83]

Answer: 0.6m

Explanation:

Given that:

force = 4.5 N

Work done = 2.7J

Distance moved by the book = ?

Since work is done when force is applied on an object over a distance, apply the formula:

work = force x distance

2.7J = 4.5N x distance

Distance = (2.7J / 4.5N)

Distance = 0.6 m

Thus, the book was moved 0.6 metres far

A wire carrying a 29.0 A current passes between the poles of a strong magnet such that the wire is perpendicular to the magnet's
Dmitrij [34]

Answer:

2.59 T

Explanation:

Parameters given:

Current flowing through the wire, I = 29 A

Angle between the magnetic field and wire, θ = 90°

Magnetic force, F = 2.25 N

Length of wire, L = 3 cm = 0.03 m

The magnetic force, F, is related to the magnetic field, B, by the equation below:

F = I * L * B * sinθ

Inputting the given parameters:

2.25 = 29 * 0.03 * B * sin90

2.25 = 0.87 * B

=> B = 2.25/0.87

B = 2.59 T

The magnetic field strength between the poles is 2.59 T
