I think it would be near the sun due.to high rays of sun
Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s
If this is a true/false question, then the above statement is false. Bowling balls may roll down hills, because they generally roll when used, but tennis balls do not roll. They are played with differently. So the statement is FALSE.
Answer:
20% of the human body float above the surface in the dead sea.
Explanation:
Given data,
The human density after inhaling, d₁ = 945 kg/m³
The human density after exhaling, d₂ = 1020 kg/m³
Therefore the average human density, d = 982.5 kg/m³
The density of the dead sea, D = 1230 kg/m³
The percentage of density of human body to the dead sea is,
P % = (982.5 / 1230) x 100 %
= 80 %
Therefore, the human body has 80% of dead sea density.
Hence, 20% of the human body float above the surface in the dead sea.
