Answer:
Polar bears (Ursus maritimus) are of special interest because of their large size, white color and position as the top-level carnivore in the remote arctic environment. They occur only in the northern hemisphere nearly always in association with sea ice. They have only two colors of fur: tan and white. Polar bears were created to withstand cold temperatures and are quite adaptable. Polar bears are ferocious and the most dangerous of bears. They can lop a person's head off with one swoop of their paw.
Answer:
11.7 m/s
Explanation:
To find its speed, we first find the acceleration of the center of mass of a rolling object is given by
a = gsinθ/(1 + I/MR²) where θ = angle of slope = 4, I = moment of inertia of basketball = 2/3MR²
a = 9.8 m/s²sin4(1 + 2/3MR²/MR²)
= 9.8 m/s²sin4(1 + 2/3)
= 9.8 m/s²sin4 × (5/3)
= 1.14 m/s²
To find its speed v after rolling for 60 m, we use
v² = u² + 2as where u = initial speed = 0 (since it starts from rest), s = 60 m
v = √(u² + 2as) = √(0² + 2 × 1.14 m/s × 60 m) = √136.8 = 11.7 m/s
I think its B because it never has a the turn over to any other side except for the west.
The SI / Metric unit of force is the ' Newton '.
1 newton is the force that accelerates 1 kg of mass at the rate of 1 m/s² .
Answer:
Explanation:
For resistances in parallel we know that the overall resistance will be smaller in the value than any individual resistance. so, in this case we are concerned about 
= 
⁺ 
where Rs is the series resistor and Rp is the parallel resistor.
so, R = 0.9M, roughly.
So, as the infernal resistance is very high as compared to the resistance conntected in parallel that is 100 Ω is not be used.
