Answer:
No, it is independent
Explanation:
As we know that car is moving horizontally
so the vertical component of the speed is zero initially
so in order to hit the ground we know that
so here we know that
on solving above equation for time
so we will say that it will not depends on the initial horizontal speed
Answer:
p = mv
Explanation:
The momentum of an object is given by the equation:
where
m is the mass of the object
v is the velocity
Since velocity is a vector, it follows that momentum is a vector as well, therefore it has a magnitude and a direction (the same as the velocity).
The SI unit of the momentum is
An important law related to the momentum is the law of conservation of momentum, which states that for an isolated system (= zero net external force on it), the total momentum of the system is conserved.
Answer:
A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.
Explanation:
A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.
Answer:
E = 12262 V/m
Explanation:
given,
Charge of the particle, q = +4.0 μC
mass of the ball, m = 5 g
Electric field, E = ?
Force due to weight
F = m g
Force due to electric field
F =q E
To balance the weight of particle both the forces must be equal
Electric field exerted on the ball will be equal to
m g = q E
E = 12262 V/m
Hence, the electric field acting in the particle is equal to E = 12262 V/m
Answer:
Law of conservation of momentum states that "The total momentum of an isolated system always remains constant"
Or
"In an isolated system the total momentum of the interacting bodies remains constant before and after collision or interaction".
