Answer:
3.34kg/min²
Explanation:
Convert to the same unit of time:
120kg/h = 2kg/min
10s = 0.6min
acceleration = change in velocity / time
a = 2/0.6 = 3.34
Change unit if needed!
Answer:
A=0.199
Explanation:
We are given that
Mass of spring=m=450 g=
Where 1 kg=1000 g
Frequency of oscillation=
Total energy of the oscillation=0.51 J
We have to find the amplitude of oscillations.
Energy of oscillator=
Where =Angular frequency
A=Amplitude
Using the formula
Hence, the amplitude of oscillation=A=0.199
Answer:
Average speed = 40.50 km/h (Approx)
Explanation:
Distance = Time × Speed
Total distance = (40/60) 50 + (8/60) 70 + (35/60) 35
Total distance = 33.33 km + 9.33 km + 20.17 km
Total distance = 62.80 km
Average speed = Total distance / Total time taken
Average speed = 62.80 / [(40+8+35+40)/60]
Average speed = 62.80 / 1.55
Average speed = 40.50 km/h (Approx)
Isostasy is the concept used to explain the dynamics of the earth's upper layers. It is considered that there is a gravitational equilibrium that exists between the earth's upper most layer, the crust, and the next layer, the mantle. The crust is said to "float" on the mantle.
Therefore, in this model, the block of wood represents the crust and the water represents the earth's mantle.
Well! see the car experiences 300 N force to the right from the engine.
It also experiences 150N force to left due to friction and air resistance
Now, we know it is the net force which will decide the car will move in which direction
We have net force=300-150=150N
which is towards right
So that means car will accelerate in right direction.
Hope it helps!!
