Answer: 4 times grease
Explanation: Force F= C · q1·q2/r². C = Coulomb's constant.
If charges double you have 2q1 and 2q2.
The box is moving in the direction of Eduardo with a force of 300N since he is pulling 300N stronger than Clara.
Answer:
Apply the following formulae horizontally And get A value for time
Remember horizontal acceleration is zero
and then to find the height apply the same above equation vertically...remember vertical initial velocity is zero
Answer:
Explanation:
PE = mgh = 60(9.8)(2.0) = 1176 J
Answer:
1.4 * 10 ^-1 Ω
Explanation:
Hi,
For this question, we gotta use the formula
R = pL/A
p = The resistivity of your material at 20°C
L = length of the wire
A = cross-sectional area
The resistivity of tungsten is 5.60 * 10^-8 at 20°C
By plugging the values, we get:
R = (5.60 * 10^-8)(2.0)/(7.9*10^-7) = 1.4 * 10 ^-1 Ω
