∆y is change in y (velocity) and ∆x is change in x (time)
So from the graph we see that ∆y is zero and ∆x is also zero (value is changing with same ratio)
∆y/∆x= slope = 0
Answer:
15.8 N
Explanation:
The component in a given direction is the magnitude of the applied force, multiplied by the cosine of the angle between its application and the direction of interest.
The horizontal component is ...
(20 N)cos(38°) ≈ 15.8 N
The buoyant force of an object which is submerged in water or any fluid is equal to the weight of the fluid displaced by an object.
why? the buoyant force goes up, and the gravitational pull goes down. <span />
Answer:
The speed of sound is greater in water ice
Explanation:
This is because water ice is in its solid form and sound travels faster in solids. This is due to its molecules being tightly packed together than in a liquid. The tightly packed molecules help sound collide quickly through it whereas in liquids the molecules aren’t tightly packed compared to a solid and the sound waves takes more time colliding through it.
Okay, i worked on this last year, a transverse wave is a wave that vibrates in the direction of its propagation, and a compression wave is a wave that travels closer together!
