2 answers:

6 0

In science, work is defined as the action that results when a force causes an object to move in the direction of the force. ... The object moves as a force is applied. The direction of the object's motion is the same as the direction of the force applied.

Answer:

The "solid force"? ... The direction of the force always seems to be coming out of the solid surface. A direction which is perpendicular to the plane of a surface is said to be normal. The force that a solid surface exerts on anything in the normal direction is called the normal force.

Calculate the applied force to the piston with a 12cm radius required to elevate a weight of 2.0X104N by the piston with a 36cm

Alex

Answer:

Option D is the correct answer.

Explanation:

Refer the figure given.

By Pascal's principle we have

$\frac{F_1}{A_1}=\frac{F_2}{A_2}$

F2 = 2 x 10⁴ N

$A_1=\frac{\pi\times (12\times 10^{-3})^2}{4}=1.13\times 10^{-4}m^2\\\\A_2=\frac{\pi\times (36\times 10^{-3})^2}{4}=1.02\times 10^{-3}m^2$

Substituting

$\frac{F_1}{1.13\times 10^{-4}}=\frac{2\times 10^4}{1.02\times 10^{-3}}\\\\F_1=2.22\times 10^3N$

Option D is the correct answer.

The frequency of a sound wave was measured to be 351 Hz. If you know that the speed of sound in air was 343 m/s, then determine

netineya [11]

Answer:

wavelength of the sound wave will be 0.977 m

Explanation:

We have given frequency of the sound wave f = 351 Hz

Speed of the sound wave v = 343 m/sec

We have to find the wavelength of the sound wave

We know that velocity of the sound wave is given by $v=\lambda f$

So wavelength of the sound wave $\lambda =\frac{v}{f}=\frac{343}{351}=0.977m$

So wavelength of the sound wave will be 0.977 m

Two objects, one with a mass of m and one with a mass of 4m are attracted to each other by a gravitational force. If the force o

Natali [406]

By 2nd Newton's Law.

F =m*g

For 1st body

Let it's force be x

thus,

x = m*g --------- eqn 1

For mass 2,

F = 4m*g

g = F/4m -------- eqn 2

For the first body's force interms of second body substitute eqn 2 into 1

x = m*(F/4m)

x = m*F

x = F/4

Therefore, the force on mass m interms of F is

F/4.

A model that shows the many interconnected feeding relationships in an ecosystem is a food .

arlik [135]

Answer:

Since ecosystems contain many different species of animals, plants, and other organisms, consumers have a variety of food sources. The pattern of feeding represented by these interconnected and branching food chains is called a food web. Figure 36-3 shows how food chains within a food web are interconnected.
