Answer:
Thrust acts on the accelerated object in the direction opposite to the applied force hence it accelerates the object in the direction opposite to the applied force. ... Its magnitude is equal to that of applied force. It always increases the velocity of the object.
Explanation:
Answer:
0.434 m
Explanation:
We are given that
Mass per unit length=
1 kg=1000 g
Tension=350 N
Fundamental frequency=f=440 Hz
We have to find the length you should make it.
We know that
Using the formula
l=0.434 m
Hence, you should make it 0.434 m long.
Higher temperatures means more energy, and a solid phase means the particles are close together. This results in highly energized particles that bump into the particles close to them, who in turn bump into more particles.
Answer:
11.82 N upward and parallel to the incline.
Explanation:
Let g = 9.81 m/s2. Gravity that acts on the bin has a magnitude of
W = mg = 3*9.81 = 29.43 N
The gravity component that is parallel to the 40 degree incline is
If the bin is moving at constant speed, then the net force (parallel to the incline) is also 0. Gravity is balanced with the push force of 26 N and the friction force.
The magnitude of friction force is 26 - 18.9 = 7.08 N
The the bin is moving down the incline, then gravity is 18.9N , friction is 7.08 N, one must create an upward force of 18.9 - 7.08 = 11.82 N parallel with the incline to balance this.
In the exosphere, there is thin air, since it is the uppermost level in the atmosphere. It is made mostly of helium and hydrogen. But, traces of other gases such as atomic oxygen and carbon dioxide can also be found in the exosphere.
