It would be the flowing charged plasma blowing off the sun's surface as solar wind that creates the magnetic field.
1. The time taken for the body to fall to ground is 4 s
2. The vertical component of the velocity when the body falls to the ground is 39.2 m/s
3. The distance from the rock when it strick the ground 10m/s is 40 m
<h3>1. How to determine the time </h3>
- Height (h) = 80 m
- Horizontal velocity = 20 m/s
- Time (t) =?
h = ut
80 = 20 × t
Divide both sides by 20
t = 80 / 20
t = 4 s
Thus, it will take the body 4 s to land on the ground.
<h3>2. How to determine the vertical component of the velocity</h3>
- Time (t) = 4 s
- Acceleration due to gravity (g) = 9.8 m/s²
- Velocity (v) =?
v = gt
v = 9.8 × 4
v = 39.2 m/s
<h3>3. How to deteremine the distance</h3>
- Horizontal velocity = 10 m/s
- Time (t) = 4 s
- Horizontal distance (s) =?
s = ut
s = 10 × 4
s = 40 m

#SPJ1
The organ that fills up with urine is the bladder.
Answer:
1. k = 183.33 N/m
2. E = 0.33 J
3. x(t) = 0.06cos(2πt)
Explanation:
1. Determine the spring constant of the spring.
To determine the spring constant, we use hooke's law:
F = kΔx
where
F is the force = 11 N
Δx is the displacement = 0.06 m
k is the spring constant
k = F/Δx
k = 11/0.06 = 183.33 N/m
2. Determine the total energy of the system
the total energy(E) = Δ = 0.5 × 183.33 × 0.06² = 0.33 J.
Therefore the total energy of the system is 0.33 J
3. Write an expression x(t) for the motion of the cart. Assume the frequency f=1Hz. Express your answer in terms of the variable t and constant pi.
The expression for the motion of the cart x(t) is given by:
x(t) = Δxcos(2πft)
where the frequency f = 1 Hz
x(t) = 0.06cos(2π ×1 × t)
x(t) = 0.06cos(2πt)
