Bird habitats include various habitat types: from the human-related environment (e.g., building area, park, rural area, farmland, and pond) to the natural-related environment (e.g., forestland, grassland, river, stream, and coastland).
The upward force of the chain on the diamond would be the tension in the chain, and this tension would have to support the weight of the 45g that hangs from the chain.
mass = 45 g = 45/1000 kg = 0.045kg
Weight = mg = 0.045 * 10 ≈ 0.45N, g ≈ 10 m/s²
<span>So the upward force is ≈ </span><span>0.45N. </span>
Answer:
36 km/h
Explanation:
If d is the total distance, then the time spent driving at 20 km/h is:
t₁ = (d/3) / 20
t₁ = d / 60
And the time spent driving at 60 km/h is:
t₂ = (2d/3) / 60
t₂ = d / 90
So the total time is:
t = t₁ + t₂
t = d/60 + d/90
t = d/36
The average speed is the total distance divided by total time:
s = d / t
s = d / (d/36)
s = 36
The average speed is 36 km/h.
The object with less mass will experience greater acceleration.
We know, their product would be constant which we know as "Force"
Hope this helps!
Answer:
216,890 J
Explanation:
We first define the Kinetic Energy Formula:
K.E =
where m is the mass of the object in kg, and v is the velocity in m/s.
Given from the information from the question, we substitute the values in to find K.E.
K.E of car =
Note that the SI unit for Energy is Joules or J.
