Answer:
Plan A
Explanation:
Acceleration in a circle is toward the center of the circle, while velocity is always a straight line that's tangent to the circle. When the boy let's go of the rope the Acceleration toward the center of the circle disappears. The v ball then follows the straight path, tangent to the circle.
Answer:
3.5
Explanation:
= Straight moment of inertia = 14 kgm²
= Tucked moment of inertia = 4 kgm²
= Straight angular velocity
= Tucked angular velocity
In this system the angular momentum is conserved
![I_1\omega_1=I_2\omega_2\\\Rightarrow \omega_2=\dfrac{I_1\omega_1}{I_2}\\\Rightarrow \omega_2=\dfrac{14\omega_1}{4}\\\Rightarrow \omega_2=3.5\omega_1](https://tex.z-dn.net/?f=I_1%5Comega_1%3DI_2%5Comega_2%5C%5C%5CRightarrow%20%5Comega_2%3D%5Cdfrac%7BI_1%5Comega_1%7D%7BI_2%7D%5C%5C%5CRightarrow%20%5Comega_2%3D%5Cdfrac%7B14%5Comega_1%7D%7B4%7D%5C%5C%5CRightarrow%20%5Comega_2%3D3.5%5Comega_1)
The factor is 3.5
Answer:
I think its radiation
Explanation:
Conduction is the transfer of heat through solids (A)
Convection is the transfer of heat through liquids or gasses (B)
Radiation is the transfer of heat through em waves (C)
Multiply 25 times 6, to get 60 seconds and that is your beats per minute. In this case it is 150 BPM.
Raising the temperature results in the radiator giving off photons of high-energy ultraviolet light. As heat is added, the radiator emits photons across a wide range of visible-light frequencies
