Answer:
Correct option C. "The two objects stick together"
Explanation:
There are two types of collision. First one is elastic collision and other one is inelastic.
In inelastic collision, the linear momentum before and after the collision is same but the kinetic energy after the collision is not constant. It is used in the form of heat, light etc.
For an inelastic collision, two objects after collision sticks together and move with a common speed. It is one of the important factor for inelastic collision.
Answer:
The value is
Explanation:
From the question we are told that
The depth of the bottom of the trench is
The depth considered is
Generally the pressure is mathematically represented as
Here is the density of water with value
=>
=>
Converting to atmosphere
=>
=>
R=10
F=R/2
F=10/2=5
F=-5(CONCAVE MIRROR)
U=-8(CONCAVE MIRROR)
HEIGHT OF OBJECT=1.5
V=?
HEIGHT OF IMAGE=?
I/F=1/U+1/V
-I/5=-1/8-1/V
-1/V=-1/5+1/8
-1/V=-8+5/40
-1/V=-3/40
1/V=3/40
V=40/3
HEIGHT OF IMAGE/HEIGHT OF OBJECT =-V/U
HEIGHT OF IMAGE=40/3*1/-8*15/10
=-20/8
=-2.5
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
Answer:
0.75kg into gram = 0.75 * 1000 = 750g
potential energy = mgh
potential energy = 750 * 10 * 0.35
potential energy = 2625 joules
