In what ways are directions slightly distorted on the gore map
Bezzdna [24]

Distorted maps attempt a compromise, cutting the terrestrial surface along some arbitrarily chosen lines, then projecting each lobe (or gore, in case of interruptions, repeat periodically along related lines like meridians), separately with lower overall deformation. Gore boundaries are often designed to fall on less important areas, like oceans.

The velocity of a 150 kg cart changes from 6.0 m/s to 14.0 m/s. What is the magnitude of the impulse that acted on it?
tensa zangetsu [6.8K]
M = 150 kg.

Final velocity, v = 14 m/s

Initial Velocity, u = 6 m/s

Impulse = <span> m(v - u)</span>
 
             = 150*(14 - 6)
           
             =  150*8 = 1200 kgm/s  or 1200 Ns<span> </span>

An anchor with a density of 700 lb/ft3 tied to a rope is submerged in water (but is not touching the bottom). It has a volume of
Ivanshal [37]

Answer:

Explanation:

Given

Density of anchor \rho _a=700\ lb/ft^3

Volume of anchor V=2.8\ ft^3

Density of water \rho _w=62.4\ lb\ft^3

Buoyancy force on submerged object is given by

F_B=\rho _W\times V\times g

F_B=62.4\times 2.8\times 32.2=5625.98\approx 5626\ approx lbf

mr Goodwill [35]

Answer

Hi,

correct answer is {D} 3.5 m/s²

Explanation

Acceleration is the rate of change of velocity with time. Acceleration can occur when a moving body is speeding up, slowing down or changing direction.

Acceleration is calculated by the equation =change in velocity/change in time

a= {velocity final-velocity initial}/(change in time)

a=v-u/Δt

The units for acceleration is meters per second square m/s²

In this example, initial velocity =2.0m/s⇒u

Final velocity=44.0m/s⇒v

Time taken for change in velocity=12 s⇒Δt

a= (44-2)/12  = 42/12

3.5 m/s²

Best Wishes!

What types of objects float on water​
Naily [24]

Explanation:

Objects like apples, wood, and sponges are less dense than water. They will float. Many hollow things like empty bottles, balls, and balloons will also float. That's because air is less dense than water.
