Answer:
I'm not sure, but "Add coefficient 2 to O2...". You didn't really write out the equation properly.
Answer:
A mountain is classified as landform that raises at least 1,000 feet or more above its surroundings areas of land.
Answer:
Their change in momentum is the same in magnitude and opposite in direction
Explanation:
The momentum of an object is defined as:
where
m is the mass of the object
v is the velocity of the object
Therefore, the change in momentum of an object is
where is the change in velocity.
During a collision, the force experienced by an object is equal to the rate of change of momentum:
where is the duration of the collision.
According to Newton's third law of motion, the force exerted by vehicle 1 on vehicle 2 during the collision is equal (and opposite) to the force exerted by vehicle 2 on vehicle 1, so
Which means
And since the duration of the collision is the same for the two vehicles, this becomes
Answer:
the weight of the astronaut on Earth is 1209.88 N
Explanation:
Given;
weight of the astronaut, W = 200 N
acceleration due to gravity on moon, g = 1.62 m/s²
Apply Newton's second law of motion to determine the mass of the astronaut;
F = ma = mg
m = F/g
m = 200 / 1.62
m = 123.457 kg
The weight of the astronaut on Earth is calculated as follows;
F = mg
where;
g is acceleration due to gravity on Earth = 9.8 m/s²
F = 123.457 x 9.8
F = 1209.88 N
Therefore, the weight of the astronaut on Earth is 1209.88 N
