1 millimeter.
1 centimeter is 1/100th of a meter (1 cent of a meter).
1 millimeter is 1/1000th of a meter.
Answer:
Explanation:
Let the initial velocity of small block be v .
by applying conservation of momentum we can find velocity of common mass
25 v = 75 V , V is velocity of common mass after collision.
V = v / 3
For reaching the height we shall apply conservation of mechanical energy
1/2 m v² = mgh
1/2 x 75 x V² = 75 x g x 10
V² = 2g x 10
v² / 9 = 2 x 9.8 x 10
v² = 9 x 2 x 9.8 x 10
v = 42 m /s
small block must have velocity of 42 m /s .
Impulse by small block on large block
= change in momentum of large block
= 75 x V
= 75 x 42 / 3
= 1050 Ns.
Explanation:
You have already determined the components of the known forces so I won't repeat your work here. Since the resultant force
and F1 are completely along the x-axis, we can conclude that

We can now solve for the magnitude of 


The angle
is then

or

Answer:

Explanation:
The acceleration of the aircraft can be found by using Newton's second law:
F = ma
where
F is the net force on the aircraft
m is the mass
a is the acceleration
For the aircraft in this problem,
F = 1184 N
m = 350 kg
Solving the formula for the acceleration, we find

Answer: When electricity flows through it.
Explanation:
The electromagnet exhibits magnetic properties only as soon as current flows through the nucleus. Namely, the electric current in the space around the electrical conductor through which it passes creates a magnetic field. Unlike a permanent magnet, which has a permanent property of magnetism, the electromagnet is a temporary magnet because the magnetic field also disappears when the current ceases.
