Answer:
If the force remains the same, the acceleration would decrease
Explanation:
According to Newton's second law, the acceleration of an object is given by
where
F is the force applied to the object
m is the mass of the object
As we see from the formula, the acceleration a is inversely proportional to the mass, m. Therefore, if the force F remains constant, this means that if the mass of the skateboarder increases, then the acceleration will decrease.
Answer:
Explanation:
Formula and givens
- λ = c / f
- λ is the wavelength
- c = the speed of light
- f = the frequency
- c = 3*10^8
- f = 7.89 * 10^14
λ = ?
Solution
λ = 3*10^8 / 7.89*10^14
λ = 3*10^8/7.89*10^14
λ = 2.36 * 10^7
λ = 236 nanometers. What you use as your solution depends on what what you have been taught.
Answer:
5 feet
Explanation:
First lets imagine that the values are in meters and kg, to make it easier for me.
--------------------------------------------------------------------------------------------------------
The force created by the teacher is 120 × 5 = 600N.
--------------------------------------------------------------------------------------------------------
The force created by the 50 kg student is 50 × 8 = 400N
--------------------------------------------------------------------------------------------------------
The force that needs to be created by the 40 kg student is 600N - 400N = 200N.
To create that force that student needs to sit 200 ÷ 40 = 5m.
So the 40 lbs student is sitting 5 feet from the fulcrum.

Answer:
C : 1.4*10^(-11) N.
Explanation:
q_1 = q_2 = 1.6 * 10^(-19)
R^2 = (1)^2 + (4)^2 = 1.7 * 10^(-17) m^2
The coulomb's law is as follows:
F_e = k*q_1*q_2 / R^2
F_e = k*q^2 / R^2
F_e = (9.0*10^9) * (1.6 * 10^(-19))^2 / 1.7 * 10^(-17)
F_e = 1.35 * 10^(-11) N
Hence, answer closes to obtained is option C : 1.4*10^(-11) N.
