Answer:
Explanation:
The problem is based on conservation of angular momentum.
Moment of inertia of the disc = 1/2 m R² , m is mass of the disc and R is its radius.
= 1/2 x 98.1 x 1.51²
= 111.84 kg m²
Moment of inertia of disc + moment of inertia of bananas + monkey
= 1/2 x 98.1 x 1.51² + 9.29 x .45 x 1.51 + 20.3 x 1.51² ( moment of inertia of banana and monkey will be equal to mass x radial distance from axis² )
= 111.84 + 6.31 +46.28
= 164.43 kg m²
Now applying law of conservation of angular momentum
= I₁ ω₁ = I₂ω₂
111.84 x 1.69 = 164.43 x ω₂
ω₂ = 1.15 rad / s
Answer:
The force originates from the tires. Tires accelerate the car. The car interior in turn accelerates the air inside the car by providing a pushing force. Thus it is the car read windows, seats and side windows that push the air forward causing it to accelerate.
Explanation:
The air inside the car is being forced forward by the car interior. This includes the rear windows, seats, side windows etc.
This accelerating force originates from the tires, and makes the car interior accelerate with the car. The air inside (since it has no direct connection to the tires) is then pushed forward by the windows, seats etc.
Answer:
The following is an example of how humans can increase biodiversity
Provide Wildlife Corridors and Connections Between Green Spaces
Use Organic Maintenance Methods and Cut Back On Lawns
Use a Native Plant Palette and Plant Appropriately
Utilize Existing Green Space Connections
Be Mindful of Non-Native Predators
The answer would be A. As the bat is swung, it gains kinetic energy. But once it hits the ball, it loses, or transfers, it’s kinetic energy to the ball.
