Answer:
a scientist examines the results and answers the lab question- last choice
Answer:You need to give more explanation sorry
Explanation:
There are no acceptable descriptions at all on that list of choices.
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.

<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>distan</u><u>ce</u><u> </u><u>cover</u><u>e</u><u>d</u><u> </u><u>:</u></h3>
★ 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:
The answer is 8.44*10^9 Newton
Explanation:
The equation for universal gravitation is:
Where:
G= 6.674×10^−11 N · (m/kg)^2
M(earth)=5.972 × 10^24 kg
M(asteroid)=5.0×10^13 kg
r=1.537*10^9 m (Calculated from average distance between moon and earth)
The force will be:
8.44*10^9 Newton
