Refers to the attachment for the answer.
Let us assume that the object of mass m is kept on the Inclined plane.
Now, there will act one force called as Component of the Weight along the Incline which is given by the Relation,
mgsinθ,
where θ is the angle which the incline makes with the surface or Angle of the Incline.
Now, If there will be no friction and the object is moving along the incline
Force = mgsinθ
⇒ ma = mgsinθ
∴ a = gsinθ
This case is valid when the angle of the Incline is greater than the angle of repose, which means the object is moving with no cause or acing of the force.
But sometimes when the object does not move without the action of force, I mean that the angle of repose is greater than the angle of the incline, then we need to apply the force so that the object can move then,
Force applied = mgsinθ
∴ a = gsinθ
It will change the cases when friction is involved.
Now, For velocity, It can be found by using the equation of Motions. Time, Distance or initial velocity, etc must be given if the question will be asked related to the velocity. So by using them, you can find that.
Answer:
Electric force, F = 20.16 N
Explanation:
It is given that,
Charge on gold nucleus,
An electron is sent at high speed toward a gold nucleus,
Distance between electron and gold nucleus,
We need to find the electric force acting on the electron. The formula for electrostatic force is given by :
F = 20.16 N
The electric force acting on the electron is 20.16 N. Hence, this is the required solution.
Answer:
1) F1
Explanation:
As the air resistant force depends on the speed of object and its orientation as it falls, it does not depend on the mass of the object. Therefore, air resistant force on 1 coffee filter is the same as the air resistant force on 3 coffee filters.
Answer:
= 4,574 10⁻⁵ m
Explanation:
The interference pattern for a two slit system is given by
d sin θ = m λ constructive interference
d sin θ= (m + ½) λ destructive interference
In general and also in this case the screen is far from the slits, so the TT-free can approach the TT
tan θ = y / L
Let's replace
d y / L = m λ constructive interference
d y / L = (m + ½) λ destructive interference
Let's start when there is constructive interference
They give us the frequency of light, let's find the wavelength
c = λ f
λ = c / f
λ = 3 10⁸ / 6.32 10¹⁴
λ = 4.7468 10⁻⁷ m
Let's take the opportunity to reduce the SI system
L = 87 cm = 0.87 m
y = 3.16 cm = 0.0316 m
Now we can find the separation of the slits
d = m λ L / Y
d = 3 4.7468 10⁻⁷ 0.87 / 0.0316
d = 3.92 10⁻⁵ m
We already have all the data, now let's use the destructive interference equation and find
d / L = (m + ½) λ
= (m + ½) λ L / d
= (3 + ½) 4.7468 10⁻⁷ 0.87 / 0.0316
= 4,574 10⁻⁵ m
Answer:
F = 2(50 N) - (50 N) = 50 N
Explanation:
The direction of F is the direction in which the two students are pushing.
