B. A car is moving 4.0 m/s to the right. The car begins to accelerate at a rate of 1.5 m/s/s, to the right. After
10 seconds, what will be the velocity of the car? For credit, show work in detail

Answer:

it weighs 237469812734t7162341873498273417234321476281736481273648123764812736481723648273648137468127364872364 million pounds :)

Explanation:

Answer:

This is a dumb question.

Explanation:

The 'sky' does not weigh anything.

Answer:

It produces 1000Ω.

Explanation:

You have to apply Voltage formula, V = I × R :

V = I × R

6 = 0.006 × R

R = 6 ÷ 0.006

R = 1000Ω

We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that  How much resistance that allows 6V battery to produce a current of 0.006 amps is

R=1000 ohms

From the Question we are told

How much resistance allows 6V battery to produce a current of 0.006 amps?

Generally the equation for Resistance mathematically given as

[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]

R=1000 ohms

Therefore

How much resistance that allows 6V battery to produce a current of 0.006 amps is

R=1000 ohms

Answer:

Explanation:

length of pipe= 32 ft

wavelength of wave λ= 8.8 m

let f be frequency

we know velocity of wave v=λf

therefore, f=v/λ = 346/8.8 = 39.31 per second or hertz

time period = 1/f = 1/39.31 = 0.02543 seconds

The frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.

Frequency is defined as the number of repetitions of waves occurring in 1 second. Frequency is also defined as the number of cycles completed in 1 second. SI unit of frequency is Hz.

The given data in the problem is;

L is the length of pipe= 32 ft

λ is the  wavelength of wave= 8.8 m

f is the frequency=?

T is the time period=?

The frequency is fine as the ratio of the speed of wave and wavelength.,

[tex]\rm f= \frac{v}{\lambda} \\\\ \rm f= \frac{346}{8.8}\\\\ \rm f= 39.31 \ Hz[/tex]

The time period is guven as the inverse of the time period.

[tex]\rm T = \frac{1}{f} \\\\ \rm T = \frac{1}{39.31} \\\\ \rm T = 0.02543\ sec[/tex]

Hence the frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.

Answer:

The acceleration the ball gets = 30 m/s²

Explanation:

The given parameters are;

The mass of the first ball that hits an object, m₁ = 0.35 kg

The mass of the object hit by the ball, m₂ = 7 kg

The acceleration given to the second object, a₂ = 1.5 m/s²

Let the a₁ represent the acceleration the ball gets

Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;

Therefore, we have;

The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N

The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁

By Newton's third law, F₁ = F₂, which gives;

m₁ × a₁ = m₂ × a₂

0.35 × a₁ = 10.5

a₁ = 10.5/0.35 = 30

The acceleration the ball gets = a₁ = 30 m/s².

Explanation:

I agree with Kathy gravity must be acting the same on both balls just because one ball is heavier doesn’t mean they will hit different times if the wooden ball was drop closer to the ground then the wooden ball would hit the ground first

Answer:

7.5 m/s

Explanation:

A red tailed hawk leaves its nest and flies 100 meters across the sky in 20 secs

Speed 1= distance/time

= 100/20

= 5m/s

When it spots a garter snake on the ground it flies 50 meters in 5 secs

Average speed= distance /time

= 50/5

= 10 m/s

Therefore the average speed of the hawk over the entire journey can be calculated as follows

= 10+5/2

= 15/2

= 7.5 m/s

Explanation:

Time=distance/speed

=600/50

=12

=600/60=10

==12-10=2 hours
