Hello,
To solve we need to know the formula for speed
The formula is D/T=S (Distance of time=speed)
Now all we have to do is plug in the numbers.
20/40= 1/2 or 0.5
SO the speed is 0.5 m/s
Have a great day!
C) volume and temperature.
Answer:
6 seconds
Explanation:
Just divide 3900 by 650 to get the amount of time.
Answer:
Electric field, in the direction of gravity.
Explanation:
Given that,
Mass of the ball, m = 0.15 g
Charge on the ball,
The ball is placed inside a uniform electric field, and is suspended against the force of gravity such that,
The electric field will be acting in the direction of gravity. Hence, this is the required solution.
