Answer:
y = 1.75 cm
Explanation:
In the double-slit experiment the equation for destructive interference is
d sin tea = (m + ½)
λ
let's use trigonometry to find the angle
tan θ = y / L
as all the experiment does not occur at small angles
tan θ = sin θ / cos θ = sin θ = y / L
we substitute
y = (m + 1/2 ) λ L / d
we calculate
y = (3 + ½) 500 10⁻⁹ 5.00 / 0.5 10⁻³
y = 1.75 10⁻² m
y = 1.75 cm
Answer:
Explanation:
Just before the box starts moving, according to Newton's first law, we have:
The sine of the angle (25°) of a right triangle is defined as the opposite cathetus () to that angle divided into the hypotenuse (W):
The cosine of the angle (25°) of a right triangle is defined as the adjacent cathetus () to that angle divided into the hypotenuse (W):
Recall that the maximum frictional force is defined as:
Replacing (3) in (1) and (4) in (2):
Replacing (7) and (6) in (5) and solvinf for :
Answer: 0.56 m/s
Explanation:
Hi, to answer this question we have to apply the formula of the conservation of momentum.
m1 v1 = m2 v2 (because the system is stationary at the beginning)
Where:
m1 = mass of the astronaut
v1= velocity of the astronaut
m2= mass of the satellite
v2= velocity of the satellite
Replacing with the values given and solving:
86 kg (2.35m/s) = 360 kg v2
202.1 kgm/s=360kg v2
202.1kgm/s /360kg =v2
v2 = 0.56 m/s
Feel free to ask for more if needed or if you did not understand something.
F = ma
F = force
m = mass
a = acceleration
4.2 m/s = a
70 kg = m
F = ?
F = 4.2*70
F = 294 Newtons
Answer would then be : Force = 294 N
Answer:
A
Explanation:
But global warming will have additional, far-reaching effects on the planet. Warming modifies rainfall patterns, amplifies coastal erosion, lengthens the growing season in some regions, melts ice caps and glaciers, and alters the ranges of some infectious diseases.
