<span>To find the amount of work done by a force acting on a moving object, we can use this simple equation: W = F * d * cos(theta) W is Work F is the force d is the distance the object moves theta is the angle between the force vector and the direction of motion We know that (F * d) is 190 joules. We can find the work done when the angle is 56°. W = F * d * cos(theta) W = (190 J) * cos(56°) W = 106 J At an angle of 56°, the work done by the force is 106 joules.</span>

Allushta [10]

Answer:

F=523712 N

Explanation:

density=mass/volume

and shape is cubic so

volume=(4)^3

volume=64 m^3

mass=835*64

mass=53440 Kg

Hydrostatic force=53440*9.8=523712 N

You place an object 30.0 cm from a concave mirror of 15.0 cm focal length. The object is 1.8 cm tall. Find the image position an
Softa [21]

Answer:30 cm

Explanation:

Given

object distance u=30\ cm

focal length of concave mirror f=15\ cm

height of object h_o=1.8\ cm

Using mirror formula

\Rightarrow \frac{1}{v}+\frac{1}{u}=\frac{1}{f}

\Rightarrow \frac{1}{v}=\frac{1}{15}-\frac{1}{30}

\Rightarrow \frac{1}{v}=\frac{2-1}{30}

\Rightarrow v=30\ cm

and magnification is

\Rightarrow m=\frac{-v}{u}=\frac{h_i}{h_o}

\Rightarrow \frac{-30}{30}=\frac{h_i}{1.8}

\Rightarrow h_i=-1.8\ cm

So height of object is same as of object .

Position :image is formed at the spot where object is placed.

The magnitude, M, of an earthquake is represented by the equation M=23logEE0 where E is the amount of energy released by the ear
vfiekz [6]

Answer:

The amount of energy released by the earthquake in joules is 4.4×10^12 J.

Explanation:

As, we have given the magnitude,

M = 2/3 Log E/Eo

where E is the amount of energy released by the earthquake in joules and Eo=10^4.4 is the assigned minimal measure released by an earthquake.

As, the magnitude is given which is 5.5 then put it in the above equation,

5.5 = 2/3 Log E/Eo

Log E/Eo = 5.5×3 / 2

Log E/Eo = 8.25

Now, we will find the amount of energy released by an earthquake:

Log E/Eo = 8.25

Taking antilog,

E/Eo = 10^8.25

But Eo is given which is Eo = 10^4.4

E/(10^4.4) = 10^8.25

E = 10^8.25 × 10^4.4

E = 4.4×10^12 J.
