Answer:10. Describe Career Connection. Career Connection is an FCCLA national program that guides students to link their options and skills for success in families, careers and communities.
The velocity is (3,000/5) = 600 miles per hour west .
Answer:
The crests of the sound wave are spaced closer together.
Explanation:
the wavelength between successive crests is decreased due to the motion of the truck in the same direction as the sound
Impulse is the change in momentum.
All we need is the momentum before and after.
Momentum = (mass) x (speed)
Before: = (80 kg) x (4.7 m/s) = 376 kg-m/s
After: = (80 kg) x (3.4 m/s) = 272 kg-m/s
Change in momentum = (376 - 272) = <span>104 kg-m/s
</span>Notice that when you work with impulse, you're USUALLY calculating
(force) x (time).
The force is in Newtons, and the time is in seconds,
so the impulse is usually in units of
Newton-seconds .
So how can I say that impulse and change of momentum are
the same thing ? Am I trying to pull a fast one on you ?
Remember that 1 Newton is 1 kg-m/s²
So (force) x (time)
= (Newton) x (second)
= (kg-m/s²) x (second) = kg-m/s .
and Momentum = (mass) x (speed) = (kg) x (m/s)
The units of impulse are the same as the units of momentum !
So when you give an object some impulse, you give it exactly
that much momentum.
When the net magnetic field is zero at a certain point, a neutral point is created.
- A place where the net magnetic field is zero is known as the magnet's neutral point.
- There is only one neutral point on the perpendicular bisector of the axis equidistant from the two bar magnets when they are arranged with their axes parallel to one another and their opposing poles facing one another.
- There are two neutral points on a line equally spaced from the axis of the magnets if two bar magnets are arranged with their axes parallel to one another and their like poles facing one another.
