option A.
Explanation:
given,
Both swings are at the same height
Start swinging at the same time
The length of the string of your friend's string is longer than yours.
Using the formula of the time period
The time period is directly proportional to Length.
If the length of the string is less time period will be less.
So, your time period is less than your friend's.
Hence, when you will complete your swing your friend will be slightly lower than you.
Hence, the correct answer is option A.
Answer:
E) 3.53 m/s
Explanation:
KE₁ + RE₁ = KE₂ + RE₂ + PE
½ mv₁² + ½ Iω₁² = ½ mv₂² + ½ Iω₂² + mgh
For a sphere, I = ⅖ mr²
½ mv₁² + ½ (⅖ mr²) ω₁² = ½ mv₂² + ½ (⅖ mr²) ω₂² + mgh
½ mv₁² + ⅕ mr² ω₁² = ½ mv₂² + ⅕ mr² ω₂² + mgh
Rolling without slipping means v = ωr.
½ mv₁² + ⅕ mv₁² = ½ mv₂² + ⅕ mv₂² + mgh
⁷/₁₀ mv₁² = ⁷/₁₀ mv₂² + mgh
⁷/₁₀ v₁² = ⁷/₁₀ v₂² + gh
Substitute:
⁷/₁₀ (5.50 m/s)² = ⁷/₁₀ v₂² + (9.8 m/s²) (3.00 m sin 25.0°)
v₂ = 3.53 m/s
They all compact like are close together
<span>A mountain is a type of constructive force. This is because the mountains are formed (or "constructed") through the convergence of land plates. When the two (or more) plates come together, they cause the land at the fault line to shift upward, leading to the formation of mountains.</span>
