Answer:
Explanation:
Let the total force be F
The force that produces motion in the x direction is given as, 
Let the frictional force be given as:
Thus, the net force is given as:
Answer: 10%
Explanation:
n this case, if the earth' mass goes up by 10%, then the force of gravity on you, or your weight, will increase by the same amount, that is 10%
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

Answer:
Woke done, W = 4156.92 Joules
Explanation:
The work done by the force can be calculated as :
is the angle between force and the displacement
It is assumed to find the work done for the given parameters i.e.
Force, F = 30 N
Distance travelled, s = 160 m
Angle between force and displacement, 
Work done is given by :
W = 4156.92 Joules
So, the work done by the object is 4156.92 Joules. Hence, this is the required solution.
We are asked in the problem to determine the <span>distance of an electron in which the electric field strength is equal to e/3. we use the gravitational formula of E = m1m2/d^2
hence,
e = m1m2/1 = k/1 =k
e/2 = k/d^2
e/2=e/d^2
d^2 = 2
d = sqrt 2 = </span><span>1.41 cm</span>
