Answer:
first one is c second one is a 3 one is d 4 one is b
Explanation:
Here,
- Initial velocity (u) = 0 (as it starts from rest)
- Final velocity (v) = 60 km/h
- Time taken (t) = 15 min
<u>C</u><u>o</u><u>n</u><u>v</u><u>e</u><u>r</u><u>t</u><u>i</u><u>n</u><u>g</u><u> </u><u>the</u><u> </u><u>quanti</u><u>ties</u><u> </u><u>into</u><u> </u><u>its</u><u> </u><u>standard </u><u>form</u><u> </u><u>:</u>
→ v = 60 km/h
→ v = ( 60 × ) m/s
→ v = ( 10 × ) m/s
→ v = m/s
→ <u>v = 16.66 m/s</u>
Also,
→ t = 15 minutes
→ t = (15 × 60) seconds
→<u> t = 900 seconds</u>
<h3><u>C</u><u>a</u><u>l</u><u>c</u><u>u</u><u>l</u><u>a</u><u>t</u><u>i</u><u>n</u><u>g</u><u> </u><u>accele</u><u>ration</u><u> </u><u>:</u></h3>
★ v = u + at
- v is final velocity
- a is acceleration
- u is initial velocity
- t is time
→ 16.66 = 0 + 900a
→ 16.66 - 0 = 900a
→ 16.66 = 900a
→ = a
→ 0.0185 m/s² = a
∴ Acceleration is 0.0185 m/s².

★ v² - u² = 2as
- v is final velocity
- a is acceleration
- u is initial velocity
- s is distance
→ (16.66)² - (0)² = 2 × 0.0185 × s
→ 277.5556 - 0 = 0.037s
→ 277.5556 = 0.037s
→ = s
→ 7501.50 m = s
∴ Distance covered is 7501.50 m .
Answer:
Torque is 140.4 N-m.
Explanation:
Mass of the gymnast, m = 53 kg
Vertical force acting on the gymnast, F = 1080 N
Distance, r = 0.13 m behind the center of mass during a forward somersault. We need to find the torque generated about the center of mass. The force is acting behind the center of mass. F = -1080 N
Torque is given by :
So, the torque generated about the center of mass is 140.4 N-m.
When the vibration is in a direction parallel to wave's motion that is a Longitudinal wave (C).
But When the vibration is in a direction perpendicular to wave's motion then it is Transverse wave.
SO my sports name would be called " Basvollball" It's where you have to hit in a volleyball into a basketball hoop, of course, the time is the same as football with increments of 5 minutes for junior high and 7 minutes for high school with halftime. Also, the ball can never touch the ground and if the ball ever hits the floor its the other's team ball. To decide which team gets the ball, a coin flip will decide it. For the point system, it depends on how far the ball is hit from so it's like basketball from 3 pointers to 2 points inside the line. If the team ever reaches 30 points without the other team scoring, the team who's winning will automatically win after the time runs out in that period or quarter. You can use every body part, as long as, the ball doesn't touch the floor, and you can only use your body to push someone, no pushing with hands or arms. You can play this sport indoors or outside whether the team has a field available. There's also a maximum of 14 players on the field, so 7 players on each team.
