Answer:
Cities near water tend to have less precipitation in the summer because the water is warmer than the air
Answer:
Explanation:
According to Kepler's second law: a line segment joining an object and the Sun sweeps out equal areas during equal intervals of time. This law is equivalent to the constancy of the angular momentum, that is to say:
Here, is the comet's mass, is its distance from the Sun, is its speed and the angle between and
The aphelion and the perihelion are the only two points in the orbit where the radius and velocity are perpendicular. Therefore, at these 2 points, the angular momentum module can be calculated as a simple product:
Rewriting for :
Answer:
This is due to the gap in between the switch. So the applied energy is not converted to current even though the resistance is still there. Hence voltage will be there, where you applied it
Explanation:
Answer:
The answer to your question is Equation vf = gt; vf = 29.6 m/s
Explanation:
Data
gravity = 3.7 m/s²
vf = ?
time = t = 8 s
Formula
vf = vo + gt
Initial speed = 0 m/s
To solve this problem we can use the equations of free fall and just substitute the data.
- Substitution
vf = 0 + (3.7)(8)
- Simplification
vf = 29.6 m/s
Answer:
0.7 kg m²
Explanation:
F = force exerted applied by muscle in a professional boxer = 2551 N
r = length of lever arm = 3.15 cm = 0.0315 m
α = angular acceleration of the forearm = 115 rad/s²
I = moment of inertia of the boxer's forearm
τ = Torque applied by muscle in a professional boxer
Torque is given as
τ = I α = r F
Inserting the values
I (115) = (0.0315) (2551)
I = 0.7 kg m²
