I will answer the ones I know...and hopefully these help!..

1). Gravity makes the object fall towards the ground! It’s the gravitational pull that brings the object back down

These motions have to do with Newton’s third law..

3). I don’t think so but I might be wrong
Cuz I think that since Earth has a large mass, it pulls things in towards it but they orbit.
Sorry if that’s wrong!

-hope I helped in a way!
Wished I coulda answered all of em

The end of a garden hose is enclosed in a mesh sphere of radius 4 cm. If the hose delivers five liters per minute, how much wate
lana [24]

Answer

0.001339 liter

Explanation:

It is given that radius = 4 cm =0.04 m

volume of sphere V=\frac{4}{3}\pi R^{3}

V=\frac{4}{3}\times 3.14\times (4\times 10^{-2})^{3}=2.674\times 10^{-4}

It is given that hose delivers five liters per minute

So the water flows through sphere per minute is given by 5×2.674×10^{-4}=0.001339 liters

. Two astronauts are 1.90 m apart in their spaceship. One speaks to the other. The conversation is transmitted to earth via elec
melomori [17]

Answer:

d= 1650 km.

Explanation:

  • Assuming that sound waves travel along a straight line at a constant speed of 346 m/s, we can find the time needed for the sound to travel the distance of 1.9 m between the astronauts, just applying the definition of average velocity, as follows:

       t = \frac{\Delta x}{v} =\frac{1.9m}{346m/s} = 5.5 msec  (1)

  • The electromagnetic waves travel in free space at the same speed of light in vacuum ( since light is a electromagnetic wave indeed), i.e., 3*10⁸ m/s.
  • Applying the same formula than in (1) we can solve for the distance d, as follows:

       d = v*t = 3e8 m/s*5.5e-3s = 1650 km (2)
