Answer:
Wavelength
Explanation:
Electromagnetic Waves have different wavelengths.
They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.
Answer:
(B) 1.17 m.
Explanation:
At the highest point, the conservation of energy equation would becomes;
K.E (initial ) = K.E + P.E;
½ m(V)^2 = ½ m(V)^2 + mgh
(m*6^2)/2 = (m * 9.81 * 1.1) + (m*V^2)/2
36/2 = (9.81 * 1.1) + v^2/2
Solving the equation;
v=√14.44 m/s
= 3.8 m/s
a = −0.6g
= -0.6*9.81
= −5.88 m/s^2
Using equation of motion,
V^2 = U^2 + 2aS
S = V^2/2a
= 14.44/12
= 1.19 m.
Answer: Asking questions
Explanation:
Scientists always start with their question before
Observing anything
Answer:
The distance from charge 5 μ C = 26.45 cm and the distance from - 4 μ C is 23.55 cm.
Explanation:
Given that
q₁ = 5 μ C
q₂ = - 4 μ C
The distance between charges = 50 cm
d= 50 cm
Lets take at distance x from the charge μ C ,the electrical field is zero.
That is why the distance from the charge - 4 μ C = 50 - x cm
We know that ,electric field is given as


Therefore the distance from charge 5 μ C = 26.45 cm and the distance from - 4 μ C is 23.55 cm.
