A man can swim with a speed of 3 m/s in still water. He crosses a river of width 100 m by swimming in the direction that will ta

Elis [28]

Explanation:

The given data is as follows.

width = 100 m, speed = 3 m/s

So, minimum time required to cross the stream is calculated as follows.

t = $\frac{100 m}{3 m/s}$

Also, in the same time the man has moved downstream by 50 meter.

Hence, distance traveled downstream is as follows.

d = velocity of river × t

$v_{river} = \frac{d}{t}$

= $\frac{50}{\frac{100}{3}}$

= $\frac{3}{2}$

= 1.5 m/s

Thus, we can conclude that the river is flowing by 1.5 m/s.

What happens when you throw a basketball up toward the hoop? If you are lucky, the ball sinks into the net. You score two points

Ray Of Light [21]

Answer:

What happens when you throw a basketball up

toward the hoop? If you are lucky, the ball sinks

into the net, scoring two points before dropping

back down to the ground. The basketball isn’t

that heavy, so why doesn’t it stay up in the air

<h2>when you throw it? Have you ever heard the</h2>

saying, “What comes up must come down”?

This saying is a simple explanation for what

causes the basketball to fall back to the ground.

It is being acted on by an invisible force called

gravity, which is the basic force in the universe

that attracts all objects to each other.

1 Gravity has existed since the beginning of the universe. It is hard to understand how or why it

works, but we know it is always there because it holds everything in the universe in place. First,

you need to understand that there is a gravitational attraction between you and Earth, between

Earth and the Moon, and between Earth and the Sun. Even though you can’t feel it, the

gravitational attraction between you and Earth is what keeps your feet planted firmly on the

ground. Imagine spinning around and around on a merry-go-round. As long as you are holding

on, then you stay on the merry-go-round, but if you ever let go, you will fly off and land on the

ground. This is a useful analogy in visualizing the gravitational attraction between Earth and

you. Earth is spinning on its axis and thanks to gravity, you are held to your position on Eart

rather than flying out into space. Explanation: this is what i can do!:)

Abigail runs one complete lap (400m) around the track, while Gabi runs a 50 meter dash in a straight line. Which runner had a gr

Ipatiy [6.2K]

Answer:

$\boxed {\boxed {\sf Gabi \ had \ greater \ displacement}}$

Explanation:

Displacement is the change in the position of an object.

Abigail runs a complete lap around the track, which is 400 meters. Even though she ran 400 meters, she has <u>no displacement.</u> If she starts and ends at the same spot, there is no change in position.

Gabi runs a 50 meter dash in a straight line. Gabi has <u>50 meters of displacement</u>. She runs in a straight line and is 50 meters away from where she began.

While Abigail ran the farther distance, <u>Gabi had the greater displacement.</u>
