Answer:
The speed of the large cart after collision is 0.301 m/s.
Explanation:
Given that,
Mass of the cart, 
Initial speed of the cart, 
Mass of the larger cart, 
Initial speed of the larger cart, 
After the collision,
Final speed of the smaller cart, 
(as its recolis)
To find,
The speed of the large cart after collision.
Solution,
Let 
is the speed of the large cart after collision. It can be calculated using conservation of momentum as :
So, the speed of the large cart after collision is 0.301 m/s.

Answer:
Potential at B would be 100V
Explanation:
The electric potential is defined as the work done to bring a unit positive charge from infinity to some point in the field.
We always determine the potential with respect to some reference point. Let the potential at A be zero. If the potential at B is V, then work done to bring charge q from A to B = qV
which is the electric potential energy.
If instead we use some charge Q, the electric potential <em>energy</em> will be QV, but the electric potential will always be V.
Answer:
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.
Answer:
The weight of an astronaut plus his space suit on the Earth is 1,931.69 N.
Explanation:
Newton's second law, called the fundamental law or fundamental principle of dynamics, states that a body accelerates if a force is applied to it. This law indicates that the net force applied on a body is proportional to the acceleration that the body acquires. The constant of proportionality is the mass of the body, so Newton's second law is expressed in the following formula:
F = m*a
Where:
-
F is the net force. It is expressed in Newton (N)
- m is the mass of the body. It is expressed in kilograms (Kg).
- a is the acceleration that the body acquires. It is expressed in meters over second squared (m/s²).
The weight of an astronaut plus his space suit on the Moon is only 319 N. Then, being:
- F= weight= 319 N
- m= ?
- a = acceleration of the Moon's gravity, whose value is 1.62 m/s²
you get:
319 N= m* 1.62 m/s²
Solving:
m=196.91 kg
The mass is an invariable quantity, regardless of the planet in which the astronaut plus his space suit on the Moon is, then you have:
- F= weight= ?
- m= 196.91 kg
- a = acceleration of the Earth's gravity, whose value is 9.81 m/s²
replacing in the definition of force:
Weight= 196.91 kg* 9.81 m/s²
Weight= 1,931.69 N
<u><em>The weight of an astronaut plus his space suit on the Earth is 1,931.69 N.</em></u>
