Give an example of a vertical motion with a positive velocity and a negative acceleration. Give an example of a vertical motion

Assoli18 [71]

Answer:

An example of positive velocity is throwing a ball upwards

An example of downward vertical velocity is when an object is dropped, for example a ball dropped from a height

Explanation:

In a vertical movement the acceleration is always downwards, therefore negative since it is created by the attraction of the Earth on the body.

An example of positive velocity is throwing a ball upwards

An example of downward vertical velocity is when an object is dropped, for example a ball dropped from a height

During normal beating, the heart creates a maximum 3.60 mV potential across 0.250 m of a person's chest, creating a 1.00 Hz elec

grandymaker [24]

Answer:

The maximum electric field strength is 0.0144 V/m.

Explanation:

Given that,

Electric potential created in the heart, V = 3.6 mV

Distance, d= 0.25 m

Frequency of the the electromagnetic wave, f = 1 Hz

We need to find the maximum electric field strength created. We know that the electric potential is given by :

$V=Ed$

E is the maximum electric field strength

$E=\dfrac{V}{d}\\\\E=\dfrac{3.6\times 10^{-3}\ V}{0.25\ m}\\\\E=0.0144\ V/m$

So, the maximum electric field strength is 0.0144 V/m. Hence, this is the required solution.

An electric slot car has a coil with 100 turns of wire. These loops have a current of 0.1 A and cover an area of 0.1 cm2. If the

Marrrta [24]

Answer:

The torque will be felt by the coil is zero

Explanation:

The torque is:

$\tau =\mu B=\mu Bsin\theta$

Where

μ is the magnetic moment = N * I * A, where N is the number of turns, I is the current and A is the area

A = 0.1 cm² = 1x10⁻⁵m²

$\mu =100*0.1*1x10^{-5} =1x10^{-4} Am^{2}$

If the angle between the area and the magnetic field is 0 (are in parallel), then:

$\tau =1x10^{-4} *1*sin0=0Nm$

allochka39001 [22]

Answer:

Function

Explanation:

This question defines a function. It is any consequence that is made up of positive structures which has a way of affecting the society in a positive way. And it also has a way of impacting structural continuity in the society. The functionalism idea has the postulation that all cultural or social phenomena is of positive function and cannot be ignored
