The distance of the object from the mirror is 3cm.

To calculate the distance of the object from the mirror, we make use of the mirror formula

<h3>Mirror formula</h3>
  • 1/f = (1/u)+(1/v)............ Equation 1

Where:

  • f = Focal length of the mirror
  • v = image distance
  • u = object distance.

Using the real is positive convention,

Given:

  • f = 5 cm
  • v = -10 cm

Substitute these values into equation 1 and solve for u

  • 1/5 = (-1/10)+(1/u)
  • 1/5+(1/10) = 1/u
  • 1/u = (2+1)/10
  • 1/u = 3/10
  • u = 10/3
  • u = 3.33
  • u = 3 cm

Hence, The distance of the object from the mirror is 3cm.

Ariana is accelerating her car at a rate of 4. 6 m/s2 for 10 seconds. Her starting velocity was 0 m/s. What was her final veloci
Studentka2010 [4]

Answer:

<h3>the answer is v=46 m/s</h3>

Explanation:

<h3>to find the final velocity we use formula from uniformly accelerated motion , equation 1, that is ; V=U+at</h3>

<h3>our given is U=0m/s</h3><h2> a=4.6m/s^2</h2><h3> t=10s</h3><h3>requaired,V=?</h3>

<h3>solution will be; V = u+at</h3>

<h3>replacing the values of each individual</h3>

<h3>V=0m/s+(4.6m/s^2)(10s)</h3><h3>V=0m/s+46m/s ;second found on the unit of acceleration canceled by the unit of time and finaly the left is m/s</h3><h3>V=46m/s</h3>

In high school, it did not seem to make a difference how much clive studied spanish; he always earned poor grades. Now that cliv
Viktor [21]

The behavior expected of Clive in the new class is " Why study?" There isn't anything I can do to improve my Spanish skills."

Learned helplessness is a theory in psychology where a person after being continuously exposed to a negative circumstance for a long time accepts the circumstance and stops trying to change the circumstance.

This theory was developed by  Martin Seligman and Steven Maier. They noticed that dogs stopped attempting to avoid getting shocks after continual exposure to the shocks. This behaviour continued even after they were placed in different circumstances.

If Clive has learned helplessness, he would believe he is poor in Spanish and he would not even make an effort in understanding Spanish. This is because he believes he is poor at Spanish.

Here are the options of this question:

a. " Spanish is a difficult subject that I am very poor at."

b. " I sure hope that my Spanish professor is better than my high school Spanish teacher."

c. " Why study?" There isn't anything I can do to improve my Spanish skills."

d. "If I spend more time studying, I'm sure I will do better than in high school."

e. " I need to find a good tutor to help me learn Spanish; I can't learn it on my own."

4. Angles C and D are supplementary angles
natita [175]

Answer:

∠C = 159°

∠D = 21°

Explanation:

∠C + ∠D = 180 (1)

∠C = 33 + 6∠D (2)

Substituting (2) to (1):

180 = 33 + 6∠D + ∠D

= 33 + 7∠D

180 - 33 = 7∠D

147 = 7∠D

<u>21 = ∠D</u>

If ∠D = 21,

∠C + 21 = 180

∠C = 180 - 21

<u>∠</u><u>C</u><u> </u><u>=</u><u> </u><u>159</u>
