Answer: Samantha has the largest centripetal acceleration of 2.4 m/s^2. Maria has only 1.69 m/s^2.
Explanation:
Answer:
Explanation:
angular acceleration α = 5 rad /s ²
θ = 1/2 α t² , θ is angle of rotation , t is time .
= .5 x 5 x 4²
= 40 rad .
θ = l / r , θ is angle formed , l is length unwound , r is radius o wheel .
l = θ x r
= 40 x .1
= 4 m .
Answer:
False
Explanation:
Much information can be gotten from sensor due to the much data being gathered.
Density = 3/5 = 0.6g/cm^3. Since the density is less than the density of water, which is 1, the object will float.
Answer: (B). Solar cell B, because it generates more power.
Explanation:
Given that,
For solar cell A
Energy = 100 Joules
Time = 3 minutes = 180 sec
Power of cell A
Power = Energy/Time
For solar cell B
Energy = 200 joules
Time = 5 minutes = 300 sec
Power of cell B
Power = Energy/Time
Hence, Solar cell B, because it generates more power.
