In which direction does centripetal force act on an object?

in the opposite direction of the tangential speed of the object
in the same direction of the tangential speed of the object
toward the outside of the circle in which the object is moving
toward the center of the circle in which the object is moving

Answers

Answer 1

Answer:

Centripetal force acts on an object toward the center of the circle

in which the object is moving.  That's perpendicular to the object's

tangential velocity.

If you use the same force to push a motorcycle as you would to push a bike, which one will have more acceleration and why? Explain using Newton’s Second Law

Answers

Answer:

the bike would because it has  less mass.

Explanation:

im learning newtons laws in class right now so that should be right

The motorcycle right? Because it is experiencing more acceleration by going way faster rather than going too slow?

A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density. formula =

Answers

Answer:

Explanation:

that should help

Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.

How are the density, volume, and mass of a substance related?

Suppose that a finite amount of substance is there having its properties as:

mass of substance = m kgdensity of substance = d kg/m³the volume of that substance = v m³

Then, they are related as:

d = m/v

The volume of the tube = π × r² × h

                                = π × (2cm)² × 27.75 cm

                                = 348.716 cm³

Mass of Argon = Mass when tube is filled - Mass when tube is empty

                        = 188.87 g - 188.25 g

                        = 0.62 g

Now, the density of the gas can be written as,

Density = Mass / Volume

            = 0.62g / 348.716 cm³

            = 1.778 × 10⁻³ gm/cm³

Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.

On January 1, Year 1, a contractor began work on a $3.2 million construction contract that is expected to be completed in 3 years. The contractor concludes that it is appropriate to recognize revenue over time using the input method based on costs incurred (cost-to-cost method). At the inception date, the estimated cost of construction was $2.4 million. The following data relate to the actual and expected construction costs: Year 1 Year 2 Year 3 Costs incurred $720,000 $1,170,000 $1,110,000 Expected future costs $1,680,000 $810,000 $0 For this long-term construction contract, the contractor needs to calculate the estimated dollar values of the revenue and gross profit (loss) to be recognized each year. Complete the contractor's long-term construction contract using the information above. Write the appropriate amounts in the associated cells. Indicate losses by using a leading minus (-) sign. Round all amounts to the nearest dollar. If no entry is necessary, enter a zero (0). Revenue Gross profit (loss) Year 1Year 2 Find the difference
