Answer:
D. 10 T
Explanation:
When a particle is moving in a magnetic field, the magnetic force provides the centripetal force that keeps the particle in circular motion.
The cyclotron period (the period the particle takes to complete one orbit) can be found to be
where
m is the mass of the particle
q is its charge
B is the magnetic field
As we see, the period is directly proportional to the mass of the particle.
In this problem, the second particle is ten times as massive as the first one:
m' = 10 m
while the speed is the same. So, the period of the second particle is
Answer:
soundproofing or absorbing
Explanation:
Acoustics is the study of waves, vibrations and sound and its most common applications lie in the sound and noise control industries. Acoustic protection is the application of soft and porous material to protect individuals against undesirable sounds and noises.
cushioned seats and carpeted floors are used in soundproofing to block the unwanted noise and sound.
The Cheapest Ways To Soundproof A Room
1. Rugs:
Rugs make excellent vibration dampeners.
2. Weather Stripping:
If you know that sound is getting into your room via the door or the windows then a very cheap and effective solution can be to use weather stripping.
3. Blankets.
4. Curtains.
5. Egg Cartons.
Homemade Soundproofing Panels
Answer:
The correct option is
a. v = 
Explanation:
Time at which the object start fall t = 0
The acceleration a is given by a = g - bV
Where V = Speed of the object
Speed V² = u² + 2·a·h
However with the drag force the object will approach terminal velocity as t becomes progressively larger whereby v will stop increasing
Option a. is the only option that has limiting value of v which is in the range of g as t increases ∴ option a. is the correct option.
v = as t increases 
→ 1 s and v→ g/b m/s
Answer:
Violet has a higher frequency (approximately 7.5×1014 Hz 7.5 × 10 14 Hz ) than red light (approximately 4.3×1014 Hz 4.3 × 10 14 Hz ). Since the speed of both waves is the same, we infer that violet has a shorter wavelength (400 nm ) than red (700 nm ).
Explanation:
hope it helps this took a lot of my time please mark brainlets!
Electrons move from the atoms in the cloth to the atoms in the balloon, causing the balloon to have a negative charge
Hope this helps!!!
