Answer:
5.4kgm/s towards the hitter.
Explanation:
Given parameters:
Mass = 0.12kg
Velocity = 45m/s
Unknown:
Momentum of the baseball = ?
Solution:
To solve this problem, we must understand that the momentum of a body is the quantity of motion it possesses.
Momentum = mass x velocity
Now insert the parameters and solve;
Momentum = 0.12 x 45 = 5.4kgm/s towards the hitter.
7 A.M
I’m pretty sure that’s it
I'd say that because of gravity and the material made the red giant it's holding all the material together to be in one piece years and years to come.
Hope that helped! <3 ^-^
Answer:
3) Dims in, Brightens out
Explanation:
The relationship between the inductance of a coil and the current is inverse.
As the rod is thrusted into the solenoid, the inductance increases, which in turn decreases the current and the bulb gets dimmer. This is also because some magnetic force is drawn away from the solenoid and the battery.
When the rod is removed, the inductance of the solenoid decreases, the current increases, and the bulb becomes brighter.
