The required mass of the planet is 8 times the mass of the earth.

Given that,
The Escape speed at the surface of a certain planet is twice that of the earth. The planet has a radius twice of the Earth. what is its mass in unit of earth's mass is to be determined.

An object with this velocity at the earth's surface will completely escape the earth's gravitational field, even after accounting for atmospheric losses.

here,
The escape velocity of the planet = 2 Escape velocity of the earth
[tex]\sqrt{{2GM_p}/r_p} = 2\sqrt{2GM_e/r_e}[/tex]
Substitute the values and square both sides,
[tex]{{2GM_p}/2r_e} = 4*{2GM_e/r_e}\\M_p = 8M_e[/tex]

Thus, the required mass of the planet is 8 times the mass of the earth.

Answer:

Explanation:

Given;

terminal voltage, V = 5.7 V, when the current, I = 0.3 A

terminal voltage, V = 5.1 V, when the current, I = 0.9 A

The emf of the generator is calculated as;

E = V + Ir

where;

E is the emf of the generator

r is the internal resistance

First case:

E = 5.7   + 0.3r -------- (1)

Second case:

E = 5.1 + 0.9r -------- (2)

Since the emf E, is constant in both equations, we will have the following;

5.1 + 0.9r = 5.7   + 0.3r  

collect similar terms together;

0.9r - 0.3r = 5.7 - 5.1

0.6r = 0.6

r = 0.6/0.6

r = 1 Ω

Now, determine the emf of the generator;

E = V + Ir

E = 5.1 + 0.9x1

E = 5.1 + 0.9

E = 6 V

Explanation:

Answer:

There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.

Explanation:

An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.

gravitational attraction

Answer:

33 N

Explanation:

Given that,

One dog pulls the chew toy with 64 N (E) and  the other pulls the chew toy with 31 N [W].

We need to find the net force acting on the chew toy. Let East be taken positive and west be taken negative. So,

[tex]F_{net}=+64+(-31)\\\\=33\ N[/tex]

So, the net force acting on the chew toy is equal to 33 N.

Angular acceleration [tex]= 0.167[/tex] rad/s^2

Explanation:

Given

Initial Angular velocity (w1) [tex]= 5[/tex] rad/s

Final Angular velocity (w2) [tex]= 0[/tex] rad/s

Time taken to change velocity from w1 to w2 [tex]= 30[/tex] seconds

Angular acceleration is equal to the change in angular velocity to the time taken for making thing change

Hence, Angular acceleration
