Potential energy is when the roller coaster rises. Kinetic energy is when the roller coaster declines.
Given:
• Mass, m = 0.200 mg
,
• Speed, v = 3.00 x 10³ m/s
,
• Time, t = 6.00 x 10^⁻⁸ s.
Let's calculate the force exerted.
Using the inpulse-momentum theroerm, we have:
impulse = change in momemntum
Where:
Impulse = force x time
change in momentum = mass x velocity.
Thus, we have:
Let's solve for the force F:
Therefore, the force exterted is 10000 N.
ANSWER:'
10000 N
T = 40.0 N
angle = 25°
Trigonometric ratios:
sin(25°) = vertical component of the force / force
cos(25°) = horizontal component of the force / force
tan (25°) = vertical compoent of the force / horizontal component of the force.
From cos(25°) you can find the horizontal component of the force:
horizontal component of the force = force * cos(25°)
The force is the tension, 40.0 N.
horizontal component of the force = 40.0 N * cos (25°) = 36.25 N
Answer: 36.25 N
Answer:
a) letting in-flowing and/or out-flowing tide flow through turbines in a dam.
Explanation:
Tidal power makes use of the energy from the tidal force and wave action in order to generate electricity. it is a predictable source of energy.
Tidal Barrages
The system allows tides to enter, seawater flows via the dam and is trapped into the basin when the tides subside and system’s gates close.
When the tides start to move out, the gates in the dam are opened up this consist of turbines and water begins to flow out, hitting the turbines this eventually turn to produce energy.
Power is produced when the tidal range, which is the difference between low and high tide, has to be more than 5 meters.
