Answer: The impulse delivered to the object is 33 N • s.
Explanation: Impulse = Change in momentum
The momentum of an object is calculated by multiplying its mass by its velocity:
Momentum = Mass x Velocity
Given:
Mass of the object = 1.5 kg
Initial velocity = +15 m/s
Final velocity = +22 m/s
Time interval = 3.5 seconds
First, we need to calculate the change in momentum:
Change in momentum = Final momentum - Initial momentum
To find the initial momentum, we multiply the mass by the initial velocity:
Initial momentum = Mass x Initial velocity
Initial momentum = 1.5 kg x 15 m/s
To find the final momentum, we multiply the mass by the final velocity:
Final momentum = Mass x Final velocity
Final momentum = 1.5 kg x 22 m/s
Now, we can calculate the change in momentum:
Change in momentum = Final momentum - Initial momentum
Change in momentum = (1.5 kg x 22 m/s) - (1.5 kg x 15 m/s)
Simplifying the equation:
Change in momentum = 33 kg m/s
Finally, we have found the change in momentum, which is equal to the impulse delivered to the object. Therefore, the impulse delivered to the object is 33 N • s.
Answer:
11 Ns
Explanation:
Impulse = change in momentum
J = Δp
J = mΔv
J = (1.5 kg) (22 m/s − 15 m/s)
J = 10.5 kg m/s
Rounded to two significant figures, the impulse is 11 Ns.

Answer: 2.878 parsecs
Explanation:
To convert astronomical units (AU) to parsecs (pc), you can use the following relationship:
1 parsec (pc) = 206,265 AU
Now, you can simply divide 594,000 AU by this conversion factor:
594,000 AU / 206,265 AU/pc ≈ 2.878 parsecs
So, there are approximately 2.878 parsecs in 594,000 astronomical units.

Answer:
doppler effect
Explanation:
When the relative motion of two bodies results in the wavelength becoming shorter this means that the bodies are getting closer. This is known as blue shift.
When the relative motion of two bodies results in the wavelength becoming longer this means that the bodies are getting farther. This is known as red shift.
Collectively this phenomenon is known as the Doppler effect.

It will take a car, 2.59 s to accelerate from 15.2 to 23.5 m/s.
What is Speed?
speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, the car has an average acceleration of 3.2 m/s².
To solve this problem, we can use the following kinematic equation:
v = u +at
where:
v is the final velocity (23.5 m/s)
u is the initial velocity (15.2 m/s)
a is the acceleration (3.2 m/s^2)
t is the time
We can rearrange this equation to solve for t:
t = (v -u)/a
substituting the values we have:
t = (23.5 - 15.2 ) / 3.2
t = 2.59375 seconds
Therefore, it will take approximately 2.59 seconds for the car to accelerate from 15.2 m/s to 23.5 m/s with an average acceleration of 3.2 m/s².

Hello!
How long will it take a car to accelerate from 15.2 m/s to 23.5 m/s if the car has an average acceleration of 3.2 m/s² ?
We have the following data:
Vf (final velocity) = 23.5 m/s
Vi (initial velocity) = 15.2 m/s
ΔV (speed interval) = Vf - Vi → ΔV = 23.5 - 15.2 → ΔV = 8.3 m/s
ΔT (time interval) = ? (in s)
a (average acceleration) = 3.2 m/s²
Formula:
Solving:
Answer:
The car will take approximately 2.6 seconds to accelerate
