Answer:

The object has 2 meter length. This means the length is any quantity with a dimension distance. The definition of the length is how long something is or amount of space. In the given data it is stated that, the object is something that has a length of 2 meter.

Let's take examples to understand.

For example a thread or a table is an object which has a total length of 2 meters.

Another example is something we are measuring it gives us a result of 2 meters of length by using a meter scale or meter tape.

Length is a measure of distance and it is a fundamental quantity. Meter is a international system of units (SI units).

Ksenya-84 [330]

Answer:

$6.29591\times 10^{-6}\ N/C^2$

Explanation:

Flux is given by

$\phi=EAcos\theta$

A = Area

$A=0.4\times 10^{-3}\times 0.6\times 10^{-3}$

E = Electric field = 76.7 N/C

Angle is given by

$\theta=90-20\\\Rightarrow \theta=70^{\circ}$

$\phi=76.7\times 0.4\times 10^{-3}\times 0.6\times 10^{-3}\times cos70\\\Rightarrow \phi=6.29591\times 10^{-6}\ N/C^2$

The flux through the sheet is $6.29591\times 10^{-6}\ N/C^2$

How can we realize that light travel in straight line ?

Norma-Jean [14]

Answer:

It can be seen from the operation of pin-hole camera, formation of shadows and eclipse.

Explanation:

The phenomenon of light traveling in a straight line is known as rectilinear propagation of light.

One this evidence can be seen from the operation of pin-hole camera, which depends on rectilinear propagation of light

Also two natural effects that result from the rectilinear propagation of light are the formation of Shadows and Eclipse.

charle [14.2K]

Answer:

She will make the mass of the smiley face twice as massive in order to keep the mobile in perfect balance.

Explanation:

mass of an object is directly proportional to the cube of its length. In this case the length is constant, the mass will also be constant for the smiley face, so that the mobile will be kept in perfect balance.

Therefore, If Anya decides to make the star twice as massive, and not change the length of any crossbar or the location of any object, she will make the mass of the smiley face twice as massive in order to keep the mobile in perfect balance.

aleksklad [387]

For a certain interval of time, an object is acted on by a constant non-zero force. For this interval of time . . . . .

A. The object is at rest. No. From F=ma, if F is not zero, the object can't remain at rest.

B. The object's velocity changes. Yes. From F=ma, if F is not zero, there must be acceleration.

C. The object's velocity can only increase. No. It might decrease.

D. The object is moving with constant velocity. No. From F=ma, if F is not zero, there must be acceleration.

E. The object is accelerating. Yes. From F=ma, if F is not zero, there must be acceleration.
