im pretty sure this is right 4. true 5. force
Answer:
1.86 × 10 ∧-3 V/m
≅ 1.9 × 10 ∧-3 V/m
Explanation:
Radius of long solenoid (R)= 3 cm
Turns per meter (n) = 2500
current flowing in coil (I) = 0.30 sin (200 t)
Time (t) = 2.5 ms
Distance at which electric field calculated (r) = 4 cm
The main solution is shown in the picture attached below.
Thank you and i hope it helps.
Answer:
acc to formula= F= G m1m2/rsq
mass of Uranus= F×r sq/G×m
M=3.00×10^25×761.4×761.4×10^6/6.67×10^ -11×3.01×10^21
=3×10^25-8×7614×7614/667×301×10^-2-11+21-2
=173918988×10^11/200767
=866×10^11(approx)
The photon
energy is the energy carried by a single proton.
The equation used for calculating photon energy is:
E = hc / λ
where h = Planck constant
c = speed of light and
λ = wavelength of photon
frequency = f = c / λ
replace c /λ with f in the equation of photon energy
E = hf
frequency = 610 thz = 6.1 x 10¹⁴hz
h = 6.26 x 10⁻³⁴ js
E = 6.26 x 10⁻³⁴ x 6.1 x 10¹⁴
<span>E = 3.8 x
10</span>⁻¹⁹ j
Answer:
He can throw it away from himself.
Explanation:
Newtons Third Law says that everything has an equal, yet opposite reaction on other objects.
