Answer:
Justin ! Justin ! ! You're in high school Physics. You've done Newton's Laws until you saw them in your sleep. When the wind rustles through the trees, you almost hear it whispering to you "F = M A". Now is the time to use that ! M=65kg. A=0.3m/s^2. F = (65)(0.3)=19.5 newtons.

What would happen if the moon were twice as big

During a total lunar eclipse, where is the Moon located?a. in the umbra b. in the penumbra c. between the Sun and Earth d. between the umbra and penumbra

Speakers A and B are vibrating in phase. They are directly facing each other, are 6.69 m apart, and are each playing a 75.0-Hz tone. The speed of sound is 343 m/s. What is the distance from speaker A to the first point on the line between the speakers where constructive interference occurs?

An electromagnetic wave is composed of electrical and magnetic energy. true or false

Do you get the same answer if you drive 1.0x10²km at each of the two speeds

Question 2 options:

True

False

Answer: False

Explanation: The Mesozoic Era was the “age of the dinosaurs.” The era ended with “The Great Extinction” which marked the end of the dinosaurs as the Cenozoic era began.

**Answer : Yes, distance measurements based on the speed of light used for objects in space.**

**Explanation : **A light year is measurement of distance that light travel in a one year.

In a one year light travels 9460000000000 kilometer.

We know that, speed of light is

and time is 31536000 seconds in 1 year

so, **distance****= speed of light X time **

Now, the light year is

**Example : The nearest star to earth is about 4.3 light year away. **

**Answer:**

v = 7 m/s

**Explanation:**

p = m × v

42 = 6 × v

6v = 42

v = 42/6

v = 7 m/s

B. friction

C. inertia

D. gravity

**The correct answer to the question is D). Gravity.**

**EXPLANATION:**

Before coming into any conclusion, first we have to understand centripetal force.

**Centripetal force is the force which is required to keep a body moving in a circular path. This force always acts along the radius and towards the centre.**

As per the question, the object is moving around the earth. As it is moving in a orbit, it needs a centripetal force which will help the object stick to the orbit.

**The centripetal force required is provided to the object by the gravitational force of earth .**

Air resistance and friction play no role in imparting centripetal force to the object.

**Hence, the correct option of this question is gravity, which is the only force that acts on an object orbiting earth.**

im pretty sure its gravity

In the frame of reference of the passengers, flight attendants,

pilot ... anybody ON the plane ... the plane isn't moving at all.

pilot ... anybody ON the plane ... the plane isn't moving at all.

c. the force decreases

b. the pressure increases

d. the volume decreases

The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.

I think the answer is A.
