The magnitude of the acceleration in the y-direction is
Explanation:
When a projectile is fired into the air, there is only one force acting on it (neglecting air resistance): the force of gravity, which pulls the projectile downward with a force of
F = mg
where m is the mass of the projectile and is the magnitude of the acceleration of gravity. This force acts along the y-direction, downward.
Since there are no other forces acting, therefore, the motion of the projectile consists of two separate motions:
- A uniform motion along the x-direction, with constant velocity
- A uniformly accelerated motion along the y-direction, with constant acceleration ()
So, the magnitude of the acceleration in the y-direction is .

Answer:
This is the electromagnetic spectrum.
Explanation:
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies. Hope this helps have a great day!
The gold was heated at rates too fast for the electrons absorbing the light energy to collide with surrounding atoms and lose energy.
Answer:
-0.34m/s
Explanation
According to the law of conservation of momentum
m1u1 +m2 u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are the initial velocities
v s the common velocity
Given
m1 = 1.5kg
m2 = 5.2kg
u1 = 2.3m/s
u2 = -1.1m/s (left direction)
Required
Final velocity v of the ball
Substitute into the formula
1.5(2.3)-5.2(1.1) = (1.5+5.2)v
3.46-5.72 = 6.7v
-2.26 = 6.7v
v = -2.26/6.7
v = -0.34m/s
Hence the final velocity of the bowling ball is 0.34m/s towards the left
Answer:
Transverse
Explanation:
Electromagnetic waves don't depend on the medium they travel through like a mechanical wave does, so they aren't mechanical. They don't oscillate (move back in forth) in the direction they travel either, ruling out compressional and longitudinal waves.
That leaves tranverse waves, the ones we're most used to, since they look very "wavelike," with smooth peaks and valleys. Electromagnic waves behave like these, oscillating in a plane perpendicular to the direction they're traveling in.
