<h3><u>Answer;</u></h3>

<em>Change in direction</em>

Acceleration involves a change in speed and <em><u>change in direction</u></em>.

<h3><u>Explanation;</u></h3>
  • Acceleration is the rate of change in velocity. <em><u>It is calculated by dividing velocity with time and measured in m/s².</u></em>
  • <em><u>Acceleration is a vector quantity, which means it has both magnitude and direction. </u></em>Since direction is the rate at which velocity of a body or object in motion changes, it means it has two components direction and speed.
  • Therefore, <em><u>acceleration is the increase in speed, or decrease in speed , or changing in direction.</u></em>

We have seen that the voltage of a concentration cell can be affected by the concentrations of aqueous components and/or tempera
NemiM [27]

Answer:

1) Magnesium metal/magnesium ion

2) Aluminum/aluminum ion

3)  Copper metal/copper(l) ion

Explanation:

The activity series is a series that shows the ease of reactivity of substances in an electrochemical cell.

The substances that are higher up in the series are more reactive in electrochemical cells.

Magnesium is the first element in the series that has the most negative redox potential  then followed aluminium.

Hence, according to Nernst,

1) Magnesium metal/magnesium ion

2) Aluminum/aluminum ion

3)  Copper metal/copper(l) ion

Consider the 65 N light fixture supported as in the figure. Find the tension in the supporting wires.
ASHA 777 [7]

By using Lami's theorem formula, the tension in the supporting wires is 48.6 Newtons

TENSION

  • Tension is also a force having Newton as S.I unit.
  • The tension in the wire will be the same.

This question can be solved by using either vector diagram or by using  Lami's theorem.

The sum of two given angles  = 42 + 42 = 84 degrees

The third angle = 180 - 84 = 96 degrees.

Below is the Lami's theorem formula

\frac{T}{sin\alpha } = \frac{T}{sin\beta } = \frac{W}{sinY}

Where

\alpha  = \beta = 42 + 90 = 132 degrees

Y = 96 degrees

W = 65 N

By using the formula, we have

\frac{T}{sin\alpha } =  \frac{W}{sinY}

T/sin 132 = 65/sin96

Cross multiply

T = 0.743 x 65.57

T = 48.56 N

Therefore, the tension in the supporting wires is 48.6 Newtons approximately.

Problem 3.2 Part A Draw the vector C⃗ =A⃗ +B⃗ .(Figure 1)
Elodia [21]
I can't answer this question without a figure. I've found a similar problem as shown in the first picture attached. When adding vectors, you don't have to add the magnitudes only, because vectors also have to factor in the directions. To find the resultant vector C, connect the end tails of the individual vectors. <em>The red line (second picture) represents the vector C.</em>

A material that conducts electricity is called a... what?
jonny [76]

Answer:

Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.

I hope it helped you...
