Answer:
<em>Distance= 187.5 m
</em>
<em>Displacement= 12.5 m</em>
Explanation:
<u>Distance And Displacement
</u>
The question doesn't say what the length of the pool is, so we are assuming two things:
The pool is 50 m long.
One lap is one pool length, i.e. 50 m
Grant swims 3 3/4 laps. If we add up the total distance is 50*(3.75)=187.5 m
Grant starts in one end, swims one pool, then swims back one pool. Right now, he has zero displacement
Then he swims another pool and returns only 3/4 of the lap, which means he still needed 1/4*50 m=12.5 to arrive at his starting point. The final displacement is the subtraction of the final position minus the initial position, i.e. 12.5 m - 0 m= 12.5 m
Answer:
Distance= 187.5 m
Displacement= 12.5 m
The solar system is bounded together by gravity, and is made up of the Sun eight planets and dwarf planets
The correct options are;
- The Sun ⇒ generates energy deep in its core through the fusion of hydrogen and into helium
- Earth ⇒ has a single moon that is surprisingly large compared to its planet
- Saturn ⇒ is orbited by at least two geologically active moons: Titan and Enceladus
- Neptune ⇒ has a large moon, Triton, that almost certainly once orbited the Sun independently
- Venus ⇒ has a surface hot enough to melt led as a result of extremely strong greenhouse effect
- Uranus ⇒ has an axis tilt that gives it very extreme seasons
- Pluto ⇒ was studied up close in 2015 by the New Horizons spacecraft.
- Mars ⇒has no surface liquid water today, but shows clear evidence of such water in the distant past
- Jupiter ⇒ has a famous storm known as the Great Red Spot
- Eris ⇒ is similar in size to Pluto and also considered a dwarf planet
- Mercury ⇒ has a greater difference in temperature between its day and night sides than any other world
Reasons:
The Sun generates energy by nuclear fusion in its cores
The size of the Moon more than a quarter of the Earth's size
Saturn moon Titan shows signs of volcanic activity
The moon Triton rotates in the opposite direction to the rotation of Neptune
Venus is the second closest planet to the Sun with a thick CO₂ atmosphere, resulting in a greenhouse effect that makes the planet 510°C hotter
Uranus has seasons that last for approximately 20 years
The New Horizons spacecraft took 9.5 years to reach Pluto after the mission was launched in 2006
Mars liquid water disappeared billions of years ago
The Great Red Spot storm has lasted for over 300 year
Eris, one of the largest dwarf planets and is further from the Sun than Pluto
The difference in temperature between the day and night sides of Mercury is 427°C - (-180°C) ≈ 607°C

Digital information can be sent through the vacuum if space, but the information must be converted to wave pulses. The correct option is B.
<h3>What is digital information?</h3>
The digital information consists of data generated by the electrical systems. For examples, computers, screens, scientific calculators or any communication devices.
The electromagnetic waves do not require medium, So, they can travel through vacuum. So, Digital information can be sent through the vacuum or space.
Therefore, the correct option is B.

Answer:
No, it is independent
Explanation:
As we know that car is moving horizontally
so the vertical component of the speed is zero initially
so in order to hit the ground we know that
so here we know that
on solving above equation for time
so we will say that it will not depends on the initial horizontal speed
Answer
given,
mass of the stick = 290 grams = 0.29 Kg
Force on the stick on one side = F = 9 N
force acting perpendicular to stick.
magnitude of acceleration
rate of change of angular momentum is equal to Force
rate of change of angular momentum = 9 N
F = m a
a = 31.034 m/s²
Direction of motion will in the direction of force application or in the direction of change of velocity
