Explanation:

Given that Force affects the body and results in different changes.

The grid that has the words related to the effects of force are :

a) Force could be a push or a pull.

c) Force has magnitude as well as direction.

e) Force acting on an object may cause a change in its state of motion or a change in its shape.

f) A force can act on an object with or without being in contact with it.

What are tectonic plates, and which of Earht's layers are they composed of?

motikmotik

The tectonic plates are made up of Earth's crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere. hope this helps :)

The potential energy of a particle as a function of position will be given as U(x) = A x2 + B x + C, where U will be in joules w

satela [25.4K]

Answer:

F = - 2 A x - B

Explanation:

The force and potential energy are related by the expression

F = - dU / dx i ^ -dU / dy j ^ - dU / dz k ^

Where i ^, j ^, k ^ are the unit vectors on the x and z axis

The potential they give us is

U (x) = A x² + B x + C

Let's calculate the derivatives

dU / dx = A 2x + B + 0

The other derivatives are zero because the potential does not depend on these variables.

Let's calculate the strength

F = - 2 A x - B

A 2.0-m wire carrying a current of 0.60 A is oriented parallel to a uniform magnetic field of 0.50 T. What is the magnitude of t

konstantin123 [22]

Answer:

The force experienced is 0.6 N

Explanation:

Given data

length of wire L= 2 m

current in wire I= 0.6 A

magnetic field B= 0.5

The force experienced can be represented as

$F= BIL$

$F= 0.5*0.6*2\\\F= 0.6 N$

Ohm's Law for electrical circuits is stated VequalsRI, where V is a constant voltage, R is the resistance in ohms and I is the

Annette [7]

Answer:

The resistance interval is $R = 1.8 \pm 0.037$

Explanation:

From the question we are told that

The voltage is V = 9 V

The current is $I = 5 \pm 0.1$

The maximum current would be

$I_{max} = 5 + 0.1 = 5.1 \ A$

The minimum current would be

$I_{min} = 5 - 0.1 = 4.9 \ A$

The maximum resistance is

$R_max = \frac{V}{I_{min}}$

$R_max = \frac{9}{4.9}$

$R_max = 1.837 \Omega$

The minimum resistance is

$R_{min} = \frac{V}{I_{max}}$

$R_{min} = \frac{9}{5.1}$

$R_{min} = 1.765 \Omega$

and $R = \frac{9}{5} = 1.8 \Omega$

The interval R lies is

$R = 1.8 \pm 0.037$
