Explanation:
General relativity is a theory of space and time. ... The central idea of general relativity is that space and time are two aspects of spacetime. Spacetime is curved when there is matter, energy, and momentum resulting in what we perceive as gravity. The links between these forces are shown in the Einstein field equations.
Answer:
c. Momentum is the product of mass and velocity
e. Momentum is a vector quantity
g. Momentum has unit of kgm/s
Explanation:
Linear momentum P
P = m .v
m =mass
v=Velocity
If mass take in kg and velocity is in m/s then momentum p will be in kg.m/s.
1. momentum is the product of velocity and mass.
2.Momentum is a vector quantity.
3.Momentum have kg.m/s unit.
So the following option are correct.
c. Momentum is the product of mass and velocity
e. Momentum is a vector quantity
g. Momentum has unit of kgm/s.
Note-
1.Joule is the unit of energy.
2.One-half the product of mass and the square of the object's speed is known as kinetic energy.
Answer:
only thing I think of when I see that is 'Just Wondering'
Explanation:
Answer:
Vr = 20 [km/h]
Explanation:
In order to solve this problem, we have to add the relative velocities. We must remember that velocity is a vector, therefore it has magnitude and direction. We will take the sea as the reference measurement level.
Let's take the direction of the ship as positive. Therefore the boy moves in the opposite direction (Negative) to the reference level (the sea).
![V_{r}=30-10\\V_{r}=20 [km/h]](https://tex.z-dn.net/?f=V_%7Br%7D%3D30-10%5C%5CV_%7Br%7D%3D20%20%5Bkm%2Fh%5D)
To solve this there is this website that I found that helps
I am in middle school so I have no idea how to solve this
but
this website may help considering u are in high school and u
(hopefully mind u)
know how to solve this
so to get there u google
"whats impact speed"
and click on the first thing there the website is ehow
