Answer:
64.5 cm
Explanation:
30 * 80 + x * 110 = 50* 190 => x = 64.5
Answer:
Decelerating
Explanation:
One arrow is moving it forward but the other arrow is using more force to move it backwards causing it to have a reduction in speed.
<span>So we want to know what is not true for the following statements about solar energy. It is true that it is used to sail ships. It is true that is not reliable. It is true that windmills are used to provide energy from wind. But it is not true that wind energy is a nonrenewable energy resource. So the correct answer is a. </span>
Answer:
108.8 m /s
θ = 21°
Explanation:
Centripetal acceleration = ω² R
=( 13 )² x .602
= 101.74 m/s²
tangential acceleration a_t = angular acceleration x R
= 64.1 x .602
= 38.58 m /s²
Total acceleration R
R² = ( 101.74 )² + ( 38.58 )²
R = 108.8 m /s
angle required be θ
Tanθ = tangential accn / radial accn
= 38.58 / 101.74
θ = 21°
