Hello there!
<span>Which of the following statements is TRUE?
Correct answer: </span>Light waves are electromagnetic waves and sound waves are mechanical waves.
Answer: 
Explanation:
IMA stands for Ideal Mechanical advantage.
The IMA of pulley system can be defined as the ratio of output force to input force.
From the given pulley system,
The input force = 
The output force = 
Hence, IMA of the given pulley system,
<span>Then, since the peak wavelength of the star Beta is 200nm, use Wein law and round 200 to the nearest WHOLE NUMBER. Hope that helps. </span>
Answer:
Explanation:
The net force on the potatoes is given by:
F= 52 - mgSintheta
F= 52- (2×9.8× Sin70°)
F = 52 -18.4
F= 33.58N
Using Newton's 2nd law
F = ma
a=F/m = 33.58/ 2 = 16.79m/s^2
Using the equation of motion:
V^2= u^2 + 2as
V^2 = 0 + 2× 16.79 x2
V^2 = 67.16
V=sqrt(68.16)
V= 8.195m/s This is the exit velocity of the potatoes
Kinetic energy, K.E = 1/2mv^2
KE= 1/2 × 2 × 8.195^2
KE = 67.16J
When there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.
<h3>What is an hazard?</h3>
Hazard refers to any obstacle or other feature which causes risk or danger.
Living organisms respond to hazards via the production of adrenaline hormone. This hormone causes a flight response away from the hazard.
Therefore, when there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.
