Answer:
a) 73.2N
b) 66.6N
c) 20.28N
Explanation:
F= mg=7.5×9.8=73.5N
Force parallel to the plane Fp= 73.5sin25= 31.06N
b) Fv= 73.5 cos25= 66.6N
c) Ff= u×Fv= 0.312×66.6=20.28N
a) Normal ForceFn= F/(cos25) - Fp - Ff = ma
1.1F -31.06-20.28=7.5×3.82
1.1F -51.84=28.65
1.1F= 28.65+51.84
F= 80.49/1.1
F= 73.2N
Answer:
λ_A = 700 nm
, m_B = m_a 2
Explanation:
The expression that describes the diffraction phenomenon is
a sin θ = m λ
where a is the width of the slit, lam the wavelength and m an integer that writes the order of diffraction
a) They tell us that now lal_ A m = 1
a sin θ = λ_A
coincidentally_be m = 2
a sin θ = m λ_b
as the two match we can match
λ _A = 2 λ _B
λ_A = 2 350 nm
λ_A = 700 nm
b)
For lam_B
a sin λ_A = m_B λ_B
For lam_A
a sin θ_A = m_ λ_ A
to match they must have the same angle, so we can equal
m_B λ_B = m_A λ_A
m_B = m_A λ_A / λ_B
m_b = m_a 700/350
m_B = m_a 2
Answer:
Explanation:
This is a projectile motion problem. We will first separate the motion into x- and y-components, apply the equations of kinematics separately, then we will combine them to find the initial velocity.
The initial velocity is in the x-direction, and there is no acceleration in the x-direction.
On the other hand, there no initial velocity in the y-component, so the arrow is basically in free-fall.
Applying the equations of kinematics in the x-direction gives
For the y-direction gives
Combining both equation yields the y_component of the final velocity
Since we know the angle between the x- and y-components of the final velocity, which is 180° - 2.8° = 177.2°, we can calculate the initial velocity.
