Answer:
Explanation:
Uranus takes about 84 years to circle the sun.
Pluto's existance has been known for 92 years. Uranius has completed 1 complete revolution. The numbers are reasonably close together and so Uranius is the answer.
Answer:
0.08 N/C
Explanation:
Electric Field: This is defined as the force per unit charge exerted at a point. The expression for electric field is given as,
E = Kq/r².............................. Equation 1
Where E = Electric Field, q = Charge, k = proportionality constant, r = distance.
making q the subject of the equation,
q = Er²/k............................... Equation 2
Given: E = 2 N/C, r = 4 m,
Substitute into equation 2
q = 2(4)²/k
q = 32/k C.
When r is increased to 20 m,
E = k(32/k)/20²
E = 32/400
E = 0.08 N/C.
Hence the electric Field = 0.08 N/C
When frequency increases, the wavelength halves.
Answer:
(from top to bottom)
350 N, 80 kg, 10 m/s^2, 80 kg, -15 m/s^2, -3000 N
Explanation:
Force = Mass*Acceleration (aka F = ma)
Using algebra, you can find the variables/unknown values.
