If you illustrate the problem, you will somewhat come up with the figure shown. The missing value is the hypotenuse of the right triangle. Using the pythagorean theorems, the value is determined to be
x = √(0.7^2 + 2.4^2)
x = 2.5 km
2.5 km is the magnitude of the distance. If you want to incorporate the displacement, the answer is reported as
2.5 km, southeast. The direction is determined from the starting point to the endpoint.
Answer:
2.5m/s²
Explanation:
Given parameters:
Mass of car = 200kg
Force on car = 500N
Unknown:
Acceleration of the car = ?
Solution:
According to Newton's second law of motion:
Force = mass x acceleration
Insert the given parameters and find the acceleration;
500 = 200 x acceleration
acceleration = 2.5m/s²
The correct answer to the question above is that the magician is seeking the wavelength of the standing wave. The part of a standing sound wave, which is its wavelength, the magician is seeking when playing a musical note of a specific pitch.
Answer:
Increase by a factor of 4.
Explanation:
The acceleration of a car moving with speed v in a circle of radius R is given by:

Now if we double the speed
in the equation above, it becomes
. Thus:

Therefore the acceleration is increased by a factor of 4.
