As long as it's on Earth, 10kg of mass weighs <em>98.1 Newtons.</em>
It doesn't matter if it's being pushed, pulled, mashed, heated on the stove, frozen in a snowdrift, painted black, shot from a cannon, hung from the ceiling, sunk in mud, licked by a puppy, or just left sitting in the back of the drawer. None of these has any effect on its weight.
To change its weight, you'd have to either change its mass ... cut a piece off of it or glue another piece onto it ... or change the strength of gravity ... like take it to the moon or to another planet.
To find how long it will take for the trip divide miles by the speed.
605 / 55 = 11
So it will take 11 hours to get to the destination.
Answer:
B. 81
Explanation:
When you multiply two numbers, round the answer to the least number of significant figures available. 67.6 has three significant figures, and 1.2 has two significant figures. So we round to two significant figures.
Answer: Technician B
Explanation: A valve overlap occurs when both the exhaust valve and the inlet valve are open at the same time.
It is also seen as the number of degrees at which both the inlet and exhaust valves are open.
Valve overlap helps in boosting the efficiency of the engine by taking advantage of the expelled pressure from the exhaust.
It is expressed mathematically in degrees of shaft rotation.
So, Technician B is very correct.
Answer:
7.5 x 10⁻⁸N
Explanation:
Given parameters:
Mass 1 = 60kg
Mass 2 = 75kg
Distance between the bodies = 2m
Unknown:
Gravitational fore = ?
Solution:
The gravitational force between the two bodies can be derived using;
F = 
G is the universal gravitation constant = 6.67 x 10⁻¹¹m³kg⁻¹s⁻²
Insert the parameters and solve;
F = 
= 7.5 x 10⁻⁸N
