The ocean's level is currently rising at about
chubhunter [2.5K]

Answer:

The sea level will be 5m higher in 1667 y (years)

Explanation:

From the question, the rate at which the ocean's level is currently rising is about 3mm per year.

First, we will convert mm (millimeter) to m (meter)

1 mm = 0.001 m

Then,

3 mm = 3 × 0.001 m

= 0.003m

That is, the rate at which the ocean's level is currently rising is about 0.003m per year.

Now, to determine how long it will take for the ocean's level be 5 m higher than now at the given rate,

If the ocean rises 0.003 m in 1 year, then

the ocean will rise 5 m in x years

x = (5 m × 1 year) / 0.003 m

x = 5 / 0.003

x = 1666.67 years

x ≅ 1667 years

Hence, the sea level will be 5m higher in 1667 y (years)

An object has an angular velocity. It also has an angular acceleration due to torques that are present. Therefore, the angular v
shusha [124]

Answer:

 α = 0 ,    w = w₀

Explanation:

Torque is related to angular acceleration by Newton's second law for rotational motion.

        τ = I α

Where τ is the torque, I the moment of inertia and α the angular acceleration.

If we apply an external torque for the sum of all torques to be zero, the angular acceleration must fall to zero

         α = 0

 

Since the acceleration is zero, the angular velocity you have at that time is constantly killed.

           w = w₀ + α t

          w = w₀ + 0
