Answer:
714.286 kg
General Formulas and Concepts:
Physics 1
- Fg = mg
Fg is gravitational force in Newtons
m is the mass of the object in kilograms
g is the gravitational acceleration of Earth: 9.8 m/s^2
Step-by-step explanation:
Step 1: Define
7000 N = Fg
g = 9.8 m/s^2
Step 2: Solve for m
1. Substitute: 7000 N = m(9.8 m/s^2)
2. Isolate m: 714.286 kg = m
Refraction is the bending of a wave as it passes at an angle from on medium to another
Answer: The electric repulsion between the two protons is stronger than the gravitational attraction.

Answer:Reducing mass i.e. water
Explanation:
Frequency For given mass in glass is given by

where k =stiffness of the glass
m=mass of water in glass
from the above expression we can see that if mass is inversely Proportional to frequency
thus reducing mass we can increase frequency
Electric bulbs are definitely luminous objects so yes, i presume so!
