Without knowing anything about their magnitudes or directions, the only thing you can always say about thier combination is that it's the "net force" on the object.
Answer: solar winds
Explanation:
<u>A solar wind is composed of high speed charged particles (plasma) ejected from the Corona- the upper atmosphere of the Sun. </u>When the temperature of the corona crosses 2 million degrees, the rapidly moving particles are not held by the Sun's gravity and release away into the solar system.
<u>The Solar wind travels throughout the solar system and carries magnetic clouds along with it. It could be damaging to life if it could reach the surface but the planet's magnetic field shields us and redirects the material beyond it. </u>
Solar wind must have reached the planet Jupiter and Dr. Tate and Dr. Ramirez would be studying its effects.
Answer:
The minumum speed the pail must have at its highest point if no water is to spill from it
= 2.64 m/s
Explanation:
Working with the forces acting on the water in the pail at any point.
The weight of water is always directed downwards.
The normal force exerted on the water by the pail is always directed towards the centre of the circle of the circular motion.
And the centripetal force, which keeps the system in its circular motion, is the net force as a result of those two previously mentioned force.
At the highest point of the motion, the top of the vertical circle, the weight and the normal force on the water are both directed downwards.
Net force = W + (normal force)
But the speed of this motion can be lowered enough to a point where the normal force becomes zero at the moment the pail reaches the highest point of its motion. Any speed lower than this value would result in the water spilling out of the pail. The water would not be able to resist the force of gravity.
At this point of minimum velocity,
Normal force = 0
Net force = W
Net force = centripetal force = (mv²/r)
W = mg
(mv²/r) = mg
r = 0.710 m
g = 9.8 m/s²
v² = gr = 9.8 × 0.71 = 6.958
v = √(6.958) = 2.64 m/s
Hope this Helps!!!
Impulse = change of momentum
Impulse = 45 x 6 = 270 Ns
P = U × I
I = P / U = 1600W / 120V = 13.4A
P = 240V × 13.4A = 3216W
If your hair blower isnt rated for 220- 230V(this is the voltage in EU) you are most likely going to burn it.
