Answer:

10000W

Explanation:

work=1000*200=200000

then

P=work/time=200000/20=10000W

What is the amplitude of the wave shown in the diagram?
Marina86 [1]
The amplitude is from the absolute value of the 0 point on the y-axis to the highest(peak) or lowest(troph) point of the wave. In this question, 3cm is the highest and -3cm is the lowest, so the amplitude is 3cm.

81. A 560-g squirrel with a surface area of 930cm2 falls from a 5.0-m tree to the ground. Estimate its terminal velocity. (Use a
Irina18 [472]

Answer:

Explanation:

Given

mass of squirrel m=560 gm

Surface area of squirrel A=930 cm^2

and the area which face A_f=\frac{A}{2}=465 cm^2

height of tree h=5 m

Coefficient of drag C=1

drag Force F_d=\frac{1}{2}C\cdot \rho \cdot A\cdot v^2

Terminal velocity is given

F_d=mg

\frac{1}{2}C\cdot \rho \cdot A\cdot v^2=mg

v=\sqrt{\frac{2\times m\times g}{\rho \times C\times A_f}}

v=\sqrt{\frac{2\times 0.560\times 9.8}{1.2\times 1\times 465\times 10^{-4}}}

v=13.9 m/s

(b)Mass of person m=56 kg

v^2-u^2=2gh

u=0

v=\sqrt{2gh}

v=\sqrt{2\times 9.8\times 5}

v=9.89 m/s

calculate the acceleration of a 41-kg crate of baseball gear when pulled sideways with a net force of 1255 N. neglect frictional
lara31 [8.8K]

In his celebrated Second Law of Motion, Newton wrote:

             Net force  =  (mass) x (acceleration).

By the process of "plugging in numbers", we can write

             1255 N  =  (41 kg) x (acceleration)

Now, after dividing each side by (41 kg), we have

             (1255 N) / (41 kg)  =  acceleration.

But  (1255N)/(41kg) = 30.61 m/s² .

So unless we have carelessly blooped the calculations somewhere,
that  30.61 m/s²  is the answer we're looking for.
