From the question, we know that after 10 seconds are passed the velocity GOES DOWN.
Based on that, we can infer that the acceleration of the arrow will be negative.
in 10 seconds, the velocity goes down 30 meter/second, (65 - 35)
so it would be 30/10 = -3 m/s/s in the same direction of travel
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.
No they don't. Without air resistance, objects fall with constant
acceleration.
On Earth, the acceleration is 9.8 m/s² ... the speed of a falling object
at any time is 9.8 m/s faster than it was 1 second earlier.
Answer:
R = 0.24 kilo-ohm
Explanation:
Given that,
Voltage, V = 12 volt
Current, I = 50 mA = 0.05 A
We need to find the resistance of the resistor. We can find it using Ohm's law. So,
V = IR
or
R = 0.24 kohm
So, the value of resistance is 0.24 kilo-ohm.
Not enough money has been invested in the science and technology behind solar power.
