Answer:
The second one is a function. {(-8, -2), (7, -2),(-9,2), (0,0)
Explanation:
Its because the y-value is repeated twice.
Hope it helps.
The answer is B because it literally says it right there, and I don't wanna make it impossibly confusing for a middle school student, lol.
Answer:
The force needed to slow down the car is, F = 67.5 N
Explanation:
Given data,
The mass of the car, m = 15 kg
The initial velocity of the car, V = 60 m/s
The final velocity of the car, v = 15 m/s
The time period of deceleration, t = 10 s
The difference in the momentum of the car is,
mV - mv = 15(60 - 15)
= 675 kg m/s
The rate of change in momentum of the car gives the force acting on it.
F = (mV - mu) / t
Substituting the values,
F = 675 / 10
= 67.5 N
Hence, the force needed to slow down the car is, F = 67.5 N
The x and y components of the velocity vector is 17.32 m/s and 10 m/s respectively.
<h3>
What is the x - component of the velocity?</h3>
The x-component of the ball's velocity is the velocity of the ball in the horizontal direction or x-axis.
The velocity of the ball in x-direction is calculated as follows;
Vx = V cosθ
where;
- Vx is the horizontal velocity of the ball
- V is the speed of the ball
- θ is the angle of inclination of the speed
Vx = (20 m/s) x (cos 30)
Vx = 17.32 m/s
The velocity of the ball in y-direction is calculated as follows;
Vy = V sinθ
where;
- Vy is the vertical velocity of the ball
- V is the speed of the ball
- θ is the angle of inclination of the speed
Vy = 20 m/s x sin(30)
Vy = 10 m/s

Answer:
The path separation is 0.10 m
Solution:
As per the question:
Mass of , m =
Ratio of the masses, R = 16:18
Velocity, v =
Magnetic field, B = 1.05 T
Now,
Mass of , m' = m\frac{1}{R} = 2.66\times 10^{- 26}\times \frac{18}{16} = 2.99\times 10^{- 26}\ kg[/tex]
Now, centripetal force here is provided by the magnetic force on the charge 'q' and is given by:
Now, for :
Now, for :
Now, the separation distance of the path is given by:
