Hello there!
The Centripetal force keeps an object moving in a circle or constant direction at the same speed.
Hope this helps!
A sphere has reflection symmetry across any plane through its center.
Answer:
The electric current through the resistor is: 7.66667 milliamps
Explanation:
Applying Ohm's law we have or solving to so now, we can replace the values given before in the equation, we need to know that the voltage across the resistor is which determine the current in the component, in this case, the resistor. After clear this topic, we get so 1 milliamps is 0,001 amps we get 7,66667 milliamps.
Explanation:
The question is incomplete. Here is the complete question.
<em>A toy rocket is launched vertically from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 98 m and acquired a velocity of 30m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The upward acceleration of the rocket during the burn phase is closest to...</em>
<em></em>
Given
initial velocity of rocket u = 0m/s
final velocity of rocket = 30m/s
Height reached by the rocket = 98m
Required
<em>upward acceleration of the rocket </em>
<em></em>
<em>Using the equation of motion below to get the acceleration a:</em>
<em></em><em></em>
<em></em>
<em>Hence upward acceleration of the rocket during the burn phase is closest to 5m/s²</em>
<em />
<em>Note that the velocity used in calculation was assumed.</em>
just analyze it in this way:
20cos30*=10( radical 3 )
20sin30*=10
