Answer:
The question continues ; Two of the particles have a negative charge: q1 = -6.3nC and q2 = -12.6nC . The remaining particle has a positive charge, q3 = 8.0nC . What is the net electric force acting on particle 3 due to particle 1 and particle 2?
Explanation:
The step by step and mathematical interpretation is as shown in the attached file.
Answer:
A
Explanation:
I think the number of kernels popped is depended on the brand of the microwave or it can be the brand of popcorn but the independent variable is the cause and the dependent variable is the effect
Answer:
The statement is true
Explanation:
The complete question is
Light bends when it changes the medium because the dielectric permittivity of the material makes the path more hard to penetrate
True or False
Solution
The given statement is true as it is the dielectric permittivity of the material which does not allow light to pass through it easily.
The medium decrease the amplitude of light and hence induces change in direction without altering its velocity or frequency.
Answer: his total speed would be 3 seconds
Explanation: because if you mulimply 10 x 3 you get 30 meaning that your answer would be 3
Weight = (mass) x (gravity)
70 N = (mass) x (9.8 m/s²)
Divide each side by (9.8 m/s²) , and you have
mass = 70 N / 9.8 m/s² = 7.14 kg.

Mass on the moon:
Mass doesn't change. It's a number that belongs to the bowling ball,
no matter where the ball goes. If the mass of the bowling ball is 7.14 kg
anywhere, then it's 7.14 kg everywhere ... on Earth, on the moon, on Mars, rolling around in the trunk of my car, or floating in intergalactic space.
However, WEIGHT depends on the gravity wherever the ball happens to be
at the moment.
The acceleration of gravity on the moon is 1.622 m/s².
So the WEIGHT of the ball on the moon is
(7.14 kg) x (1.622 m/s²) = 11.58 Newtons
That's only about 16% of its weight on Earth.
