WILL GIVE BRAINLIEST!! Part 1: Other than distance from the sun, which factor affects the temperature of a planet?

1 answer:

8 0

The thickness of the ozone layer (for earth) and the atmosphere.
Mercury is the closest planet to the sun but it isn’t the hottest because it has no atmosphere. Although Venus is the second planet from the sun, it is the hottest because of it’s thick atmosphere and the clouds that trap heat in.

In solving a physics problem you end up with m in the numerator and m/s in the denominator. The units for your answer are :_____

Vladimir [108]

Answer:

Explanation:

It is given that, a physics problem you end up with m in the numerator and m/s in the denominator. It would mean that,

$\dfrac{\text{numerator}}{\text{denominator}}=\dfrac{m}{m/s}$

m is metre and s is second

$=\dfrac{m}{\dfrac{m}{s}}\\\\=\dfrac{s}{1}$

so, the unit of the answer is s.

8). A rubber band is storing more elastic energy in it when it's stretched.
It's the work you had to do to stretch it.

9). Radio, TV, microwave, infrared (heat), visible light, ultraviolet light, X-rays,
and gamma rays are all part of the electromagnetic spectrum, and all of them
carry energy from one place to another.

Suppose that when you move the north pole of a bar magnetic toward a coil it induces a positive current in the coil. The strengt

dolphi86 [110]

Answer:

a) A positive current will be induced in the coil

Explanation:

Electromagnetic induction is the induction of an electric field on a conductor due to a changing magnetic field flux. The change in the flux can be by moving the magnet relative to the conductor, or by changing the intensity of the magnetic field of the magnet. In the case of this electromagnets, the gradual increase in the the electromagnet's field strength will cause a flux change, which will in turn induce an electric current on the coil.

According to Lenz law, the induced current acts in such a way as to negate the motion or action that is producing it. A positive current will be induced on the coil so as to repel any form of attraction between the north pole of the electromagnet and the coil. This law obeys the law of conservation of energy, since work has to be done to move the move them closer to themselves.

Set up a parallel circuit with three resistors. Set up the battery to be 9 V, one resistor at 10 Ohms, the other at 21 Ohms, and

valina [46]

In a parallel circuit, the equivalent resistance is the reciprocal of (the sum of the individual reciprocals).

1/R = 1/10 + 1/21 + 1/13

1/R = 0.225 mhos

R = 4.45 ohms

I = V / R

The total current out of the battery is

I = (9v)/(4.45ohms)

I = 2.02 Amperes

As the total current leaves the battery, it splits into 3 paths, and each resistor gets part of it. The 10ohm resistor gets the most current; the 21ohm resistor gets the least current. After flowing through the resistors, the 3 currents join and add up to 2.02 Amperes again, and the same current returns to the battery.

Each resistor has the same 9v of EMF across it.
