Katie is making a strawberry milkshake in her blender. A 0.05kg strawberry is rapidly spun around the inside of the container with a speed of 11.0 m/s, held by a centripetal force of 12.0 N. What is the radius of the blender at the strawberry’s location? Round answers to two decimal places.
Answer:
The radius of the blender is approximately 0.5041[tex]\bar 6[/tex] meters
Explanation:
The given parameters are;
The mass of the strawberry, m = 0.05 kg
The speed with which the strawberry is spun, v = 11.0 m/s
The centripetal force holding the strawberry = 12.0 N
The formula for the centripetal force, [tex]F_c[/tex], is given as follows;
[tex]F_c = \dfrac{m \cdot v^2}{r}[/tex]
Where;
r = The radius of the centripetal rotation, which is the radius of the blender
[tex]\therefore r = \dfrac{m \cdot v^2}{F_c}[/tex]
Substituting the values gives;
[tex]\therefore r = \dfrac{0.05 \times 11^2}{12} = \dfrac{121}{240} \approx 0.5041 \bar 6[/tex]
The radius of the blender, r ≈ 0.5041[tex]\bar 6[/tex] meters.

1. A ball rolls off of a table with a speed of 3.2 m/s. The table is 1.6 m high.
a) When does the ball hit the ground? (time)
b) How far away from the base of the table does the ball travel?
c) With what vertical speed does the ball hit the floor?
Answer:
Explanation:
for vertical displacement h = 1.6 , let time taken be t , initial vertical velocity = 0
h = ut + 1/2 g t²
= 1/2 g t²
1.6 = .5 x 9.8 x t²
t² = .3265
t = .57 s
b )
velocity in horizontal direction = 3.2 m /s
horizontal displacement
= 3.2 x .57 = 1.82 m
c )
for vertical movement
v = u + gt
= 0 + 9.8 x .57
= 5.58 m /s

If it takes a planet 2.8 × 108 s to orbit a star with a mass of 6.2 × 1030 kg, what is the average distance between the planet and the star?
Answer:
9.36*10^11 m
Explanation
Orbital velocity v=√{(G*M)/R},
G = gravitational constant =6.67*10^-11 m³ kg⁻¹ s⁻²,
M = mass of the star
R =distance from the planet to the star.
v=ωR, with ω as the angular velocity and R the radius
ωR=√{(G*M)/R},
ω=2π/T,
T = orbital period of the planet
To get R we write the formula by making R the subject of the equation
(2π/T)*R=√{(G*M)/R}
{(2π/T)*R}²=[√{(G*M)/R}]²,
(4π²/T²)*R²=(G*M)/R,
(4π²/T²)*R³=G*M,
R³=(G*M*T²)/4π²,
R=∛{(G*M*T²)/4π²},
Substitute values
R=9.36*10^11 m

Is static electricity more harmful than it is helpful or vice versa
Answer:
You might even see a spark if the discharge of electrons is large enough. The good news is that static electricity can't seriously harm you. Your body is composed largely of water and water is an inefficient conductor of electricity, especially in amounts this small. Not that electricity can't hurt or kill you.

How many times more gravitational potential energy would the same lander have on top of a 350-m hill on Earth? It would have times more gravitational potential energy
Answer:
6
Explanation:
Just did it.
The gravitational potential energy would the same lander have on top of a 350-m hill on Earth is 6.
What is gravitational potential energy?If an object is lifted, work is done against gravitational force. The object gains energy.
The equation for calculating gravitational potential energy is
GPE =mgh
where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.
The heavier the particle and the higher it is over the ground, the more gravitational potential energy it holds. Gravitational potential energy increments as weight and level increments.
Given is the height of hill h = 350m.
Thus, the same lander will have the the potential energy 6 times more.
