Answer:
LOL
Explanation:
IMAGINE POSTING UR CLASSWORK LOLL
V = I · R
Voltage = (current) · (Resistance)
Voltage = (250 A) · (2.09 x 10⁴)
Voltage = 5,225,000 volts .
I may be out of line here, but I'm pretty sure
that the resistance is 2.09 x 10⁻⁴ .
Then
Voltage = 0.05225 volt (not 5 million and something)
1) If the object changes directions with the same speed, it will be changing its velocity, because velocity is a vector, which depends on both magnitude and direction. Speed is just magnitude regardless of direction.
2) Rotational motion.
Answer:
The minimum force is required is, f = 0.3 mg Newton
Explanation:
Given data,
The coefficient of the static friction, μₓ = 0.3
Let the mass of the wheel is, m = M kg
The minimum force required to set the wheel in motion is equal to the force of static friction. This amount of force can be applied tangentially to the wheel in a vertical direction to set the wheel in motion.
<em> Fₓ = μₓ. F</em>
Where F is the normal force acting on the wheel and it is equal to mg.
Therefore, the minimum force is required is, f = 0.3 mg Newton
The forces that act on the beam are gravity and tension in the cable .
Gravity can be defined as the force that exists almost among all material objects that exist in the universe . Gravity is operating among objects of all sizes starting from subatomic sized particles to clusters of galaxies .It is the force that causes the free fall of an apple from the tree on the ground and also the movement of planets around the sun .
Tension can be defined as a force along the length of a medium , the force here is especially carried by a flexible medium such as a rope or a cable . The SI unit of tension is Newton per meter .
The forces that act on the beam are gravity and tension in the cable .
