The rotational kinetic energy term is often called the kinetic energy in the center of mass, while the translational kinetic ene

weqwewe [10]

Answer:

Explanation:

The total kinetic energy is the sum of the kinetic energy in the center of mass (Rotational Kinetic energy) plus the kinetic energy of the center of mass( Translational Kinetic Energy).

The formula

$K_{tot} = K_{t} +K_{r}$ is applicable only when

The moment of inertia must be taken about an axis through the center of mass.

The deepest point in the ocean is 11 km below sea level, deeper than Mt. Everest is tall.

34kurt

The pressure at the depth 11 km below sea level can be calculated using

P=ρgh

P is pressure, ρ is the density of the fluid; g is the gravitational constant, h is the height from the surface, or depth that the object is submerged.

P = ( 1000 kg/ m3) ( 9.81 m.s2)( 11 000m) + 1 atm

P = 107,910,000 pa ( 1 atm/ 101 325 Pa) + 1 atm = 1066 atm

Duplain st. is 300m long and runs from west to east between Baron and Burkey. If keith is strolling east from Baron at an averag

nadezda [96]

Answer:

Time, t = 2 minutes

Explanation:

Given that,

Length of Duplain st. d = 300 m = 0.3 km

If keith is strolling east from Baron at an average velocity of, v = 3 km/hr

Sue is power-walking west from Burkey at an average velocity of, v' = 6 km/hr

To find,

How long will it take them to meet ?

Solution,

When both objects are travelling in opposite direction, then the total speed is given by :

V = v + v'

V = 3 km/hr + 6 km/hr

V = 9 km/hr

Let t is the time taken will it take them to meet. It can be calculated as :

$t=\dfrac{d}{V}$

$t=\dfrac{0.3\ km}{9\ km/hr}$

t = 0.033 hour

t = 1.98 minutes

i.e. t = 2 minutes

So, they will take 2 minutes to meet. Hence, this is the required solution.
