It takes you 10 seconds and 100 n of force to move a shopping cart 10 meters to the checkstand. what is your power?

Stells [14]

Power = Work/Time =(Force* Displacement)/Time

Power = (100N* 10m)/10s = 100 Watts

1. The arctic tern flies from the Arctic to the Antarctic and back every year, a total distance of 22,000 miles! In late summer,

NikAS [45]

Answer:

The average velocity that these birds travel is 122.22 miles per day to the south.

Explanation:

Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.

Speed is expressed mathematically as the quotient between distance and time:

$v=\frac{d}{t}$

where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.

In this case:

d= 11,000 miles
t=3 months= 90 days ( considering that in 1 month there are 30 days)

Replacing:

$velocity=\frac{11,000 miles}{90 days}$

velocity = 122.22 $\frac{miles}{day}$

<u><em>The average velocity that these birds travel is 122.22 miles per day to the south.</em></u>

How does the kinetic theory explain how you can smell coffee and bacon at thrm?

maksim [4K]

"• Diffusion - coffee and bacon particles are floating around
• They do not interact/blend with each other
• Because of fluidity, the particles are gliding past each other and filling the open space within the nose."

A slingshot fires a pebble from the top of a building at a speed of 17.5 m/s. The building is 31.5 m tall. Ignoring air resistan

Jlenok [28]

Answer:

The speed with which the pebble strikes the ground is 30.4m/s

Explanation:

Initial velocity (u) = 17.5m/s, height (h) = 31.5m, acceleration due to gravity (g) = 9.8m/s^2

V^2 = u^2 + 2gh = 17.5^2 + 2×9.8×31.5 = 306.25 + 617.4 = 923.65

V^2 = 923.65

V = √923.65 = 30.4m/s
