Answer:
speed in km/min:
0.3km/min
speed in km/h:
18km/h
speed in m/s:
5m/s
Explanation:
the average speed is defined as:
where is the speed, is the distance traveled, and is the time
according to the statement:
and
(10 minutes are equal to a sixth of an hour which is 600 seconds)
Because the units in which the speed is required are not indicated, here are some options for the answer:
Depending on the units in which you need the speed, are the quantities you should use.
Speed in km / h (kilometers per hour):
speed in m / s (meters per second):
or the speed in km/min (kilometers per minute)
Answer:
A. It makes astronauts weightless.
Explanation:
Gravity does not make astronauts feel weightless. Astronauts are weightless because they are orbiting at the same rate as their shuttle.
Although the force of gravity weakens as one moves away from the earth surface, it does not mean that this force is absent in orbit
- Gravitational force has a constant acceleration value near the earth surface which is commonly known to be 9.8m/s².
- It is a force of attraction tending to hold and bind bodies together so far they have mass.
- This force keeps every thing from escaping space-ward from the earth surface.
<span>The weight of the rock is 138n when accelerating downward at 3.5m/ s2.Weight is a measurement of the force of gravity on an objects mass. Therefore as long as the force of gravity is the same and the mass of the rock is the same the weight should also be the same.</span>
Precision because it’s the answer
The answer is around 7.
As the acid and the base are of equal strength, they neutralize each other and the resulting solution is neutral (pH≈7).
Hope this helps you!
