Heather performs an experiment to measure the acceleration of an object due to earths gravitational and discovers the acceleration of an object is 10.91 meters per second. The actual acceleration of the object is 9.80 meters per second.

Answers

Answer 1

The percentage error in the acceleration is 11.3%.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The actual acceleration of the object is 9.80 meters per second.

The acceleration of an object is 10.91 meters per second.

Now,

Percentage error.

= (Experiment acceleration - Actual acceleration) / Actual acceleration x 100

= (10.91 - 9.80) / 9.80 x 100

= 1.11 / 9.80 x 100

= 11.33 %

Thus,

The percentage error is 11.3%.

Stock for the Jones Corporation starts with a value of $39.63 and gains $0.30 in value per month. Stock for the Overton Company starts with a value of $24.45 and gains $0.80 in value per month. When are the two stocks nearly equal in value?
A After 3 months
B After 4 months
C After 15 months
D After 30 months

Answers

Answer:

answer is d

Step-by-step explanation:

if u do the math the nearest u can get is 0.80x30=24

The time required for the two stocks of Jones Corporation and Overton Company to be nearly equal in value, is 30 months.

What is stocks?

A stock is the portion of ownership of a firm, corporation etc which gives the security of asset of the property.

Stock for the Jones Corporation starts with a value of $39.63 and gains $0.30 in value per month.

Stock for the Overton Company starts with a value of $24.45 and gains $0.80 in value per month.

Let after the x month's these two stocks nearly equal in value.

[tex]39.63+0.30\times x=24.45 +0.80 \times x[/tex]

Solve it further,

[tex]0.80 \times x-0.30\times x=39.63-24.45 \\0.50 \times x=15.18\\x=\dfrac{15.81}{0.50}\\x=30.36[/tex]

Hence, the time required for the two stocks of Jones Corporation and Overton Company to be nearly equal in value, is 30 months.
