A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.
Answer:
145.52137 m/s
1.4 m
0.7 m
60.6339 Hz
121.2678 Hz
Explanation:
T = Tension = 120 N
= Linear density = 
m = Mass of wire = 6.8 g
L = Length of wire = 1.2 m
n = Number of loops
Velocity is given by
The speed of waves on the wire is 145.52137 m/s
Wavelength is given by
The wavelength of the waves that produces one-loop standing waves is 1.4 m
The wavelength of the waves that produces two-loop standing waves is 0.7 m
Frequency is given by
The frequency of the waves that produces one-loop standing waves is 60.6339 Hz
The frequency of the waves that produces two-loop standing waves is 121.2678 Hz
Answer: The velocity with which the sand throw is 24.2 m/s.
Explanation:
Explanation:
acceleration due to gravity, a = 3.9 m/s2
height, h = 75 m
final velocity, v = 0
Let the initial velocity at the time of throw is u.
Use third equation of motion
The velocity with which the sand throw is 24.2 m/s.
True because energy can change its speed because of temperature and also its direction
Answer: F = 1391 N
Explanation:
The information given to you are:
Mass M = 1300 kg
Acceleration a = 1.07 m/s^2
The magnitude of the force striking the building will be
F = ma
Where
F = force
Substitute mass M and acceleration a into the formula
F = 1300 × 1.07
F = 1391 N
Therefore, the wrecking ball strikes the building with a force of 1391 N
