How does centripetal force act on a satellite in orbit?

You're at Gravitional Force! I got this question on my test last year. Hold on

A satellite is any body orbiting that is moving around the sun. Since the body is moving it is accelerating with a constant velocity. According to Newton's 2nd law of motion "An object which experiences an acceleration must also be experiencing a net force. The direction of the net force is in the same direction as the acceleration."

A satellite that is moving along a circular must have force acting on it or it will move on in a straight line. This force is perpendicular to the motion of the circle that us towards the motion. [Newton's 1st law- the law of inertia].

The presence of an unbalanced force is required for objects to move in circles. As well as acceleration and resultant force

a 20 of of ice at 0c is dropped into water at boiling point, specific heat capacity of water =4200 J/kg•c, sepesific latent heat

Contact [7]

Answer:

15 KJ

Explanation:

The quantity of heat (Q) required is given as:

Q = mcΔθ + mL

where m is the mass of ice, c is its specific heat capacity, L is its specific latent heat andΔθ is the change in temperature.

Given: m = 20g, temperature of ice = 0 $^{o} C$ , specific heat capacity of water = 4200 J/kg $^{o} C$ , latent heat of fusion of ice = 3.3 x 10^(5) J/kg, temperature of water = 100 $^{o} C$ .

Q = m (cΔθ + L)

= 0.02(4200 x (100) + 330000)

= 0.02(420000 + 330000)

= 0.02 (750000)

Q = 15000

Q = 15000 Joules

Q = 15KJ

The quantity of heat needed to complete the conversion is 15 KJ.

Calculate the average speed (in km/h) of a car stuck in traffic that drives 12 kilometers in 2 hours.

Vilka [71]

This is a trick question, isn't it? If a car is stuck in traffic, it doesn't matter how fast it can travel, because it isn't moving at all. Therefore the average speed would be zero, right?

A simple pendulum has a period of 3.45 second, when the length of the pendulum is shortened by 1.0m, the period is 2.81 second c

den301095 [7]

Answer:

Original length = 2.97 m

Explanation:

Let the original length of the pendulum be 'L' m

Given:

Acceleration due to gravity (g) = 9.8 m/s²

Original time period of the pendulum (T) = 3.45 s

Now, the length is shortened by 1.0 m. So, the new length is 1 m less than the original length.

New length of the pendulum is, $L_1=L-1$

New time period of the pendulum is, $T_1=2.81\ s$

We know that, the time period of a simple pendulum of length 'L' is given as:

$T=2\pi\sqrt{\frac{L}{g}}$ -------------- (1)

So, for the new length, the time period is given as:

$T_1=2\pi\sqrt{\frac{L_1}{g}}$ ------------ (2)

Squaring both the equations and then dividing them, we get:

$\dfrac{T^2}{T_1^2}=\dfrac{(2\pi)^2\frac{L}{g}}{(2\pi)^2\frac{L_1}{g}}\\\\\\\dfrac{T^2}{T_1^2}=\dfrac{L}{L_1}\\\\\\L=\dfrac{T^2}{T_1^2}\times L_1$

Now, plug in the given values and calculate 'L'. This gives,

$L=\frac{3.45^2}{2.81^2}\times (L-1)\\\\L=1.507L-1.507\\\\L-1.507L=-1.507\\\\-0.507L=-1.507\\\\L=\frac{-1.507}{-0.507}=2.97\ m$

Therefore, the original length of the simple pendulum is 2.97 m

What is primary succession?

dangina [55]

Answer:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
