When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
<h3>
Normal reaction of the box</h3>
The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.
Fn = Wcosθ
<h3>when the angle of the ramp = 30⁰</h3>
Fn = Wcos(30)
Fn = 0.866W
<h3>when the angle of the ramp = 45⁰</h3>
Fn = W x cos(45)
Fn = 0.7071W
Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

Answer:
The values is
Explanation:
From the question we are told that
The slit distance is
The wavelength is
At the first half of the screen from the central maxima
The number of bright spot according to the condition for constructive interference is
For maximum number of spot
So
Now for the both sides plus the central maxima we have
substituting values
Answer:
Explanation:
es por el rosamiento, también depende de q suelo si es liso se mueve pero si es áspero se va a detener
Although the way the curve
upon the introduction of chemicals slopes downward it suggests a release,
similarly the upward slope of the second picture upon the introduction of
chemicals suggests a build up or absorption of said energy.
<span>Since the products have
more energy, this reaction is endothermic, meaning heat needs to be added. </span><span>
<span>478-432=46kJ of energy absorbed.</span></span>
Answer:
The mass of the beam is = 29 kg.
Explanation:
A beam with mass 40 kg is shown in figure. Point S is the support point. Point B is the middle point on the beam where mass of the beam acts.
Taking moment about Point S
40 × 21 = × 29
= 29 kg
Therefore the mass of the beam is = 29 kg.
