Answer:
<em>The Hamster in a friction less exercise can move as fast as 10m/s at a constant speed for wheel system</em>
Explanation:
<em>If the Energetic hamster keeps running faster, with less friction for a wheel system, there would be no limit for the hamster, until it starts approaching a light speed. A torque is not applied by The hamster to the wheel to move it, because the torque its self is a force, the torque is not a force that is stored up, it’s the angular velocity that is stored </em>
<em>
The relationship between a linear velocity and angular velocity is stated below
</em>
<em>V= r w
</em>
<em>If the hamster can move its leg in a fast way he can get to 10 m/s for a wheel system, finally, the hamster do nothing more than to so in the wheel at a speed that is constant.
</em>
<em>Furthermore, the initial torque that is provided by the hamster deceases, then when the speed increases, the hamster will move faster as it can. </em>
Answer:
Basically W = mg, as you can see, W varies directly as m where g is a constant (9.81 m s^-2 for Earth) , this explains why the more mass an object has,the greater its weight
Explanation:
Answer:
2Ω
Explanation:
If a 18Ω resistance is cut into three equal parts each of the resistance will be 18Ω/3 = 6Ω
Equivalent ratio in parallel is expressed as:
1/R = 1/6 + 1/6 + 1/6
1/R = 3/6
Cross multiply
3R = 6
R = 6/3
R = 2Ω
Hence the required equivalent resistance is 2Ω
It's simple.
We know force is the rate of change in momentum.
So F=(mv-mu)/t or F=m(v-u)/t
=1200*(25-10)/5=3600N
