Answer:
The power will be "3.92×10⁹ Watts". A further explanation is given below.
Explanation:
The given values as per the question,
Rate,
= 8 million kg
Distance,
= 50 m
Gravity,
= 9.8 m/s²
As we know,
The power will be:
⇒ [tex]Power = Rate\times Distance\times Gravity[/tex]
On putting the values, we get
⇒ [tex]= 8\times 10^6\times 50\times 9.8[/tex]
⇒ [tex]=3.92\times 10^9 \ Watts[/tex]

A car accelerates from rest at a rate of 4 m/s’2 . How many seconds will it take the car to reach a final speed of 16m/s
Answer:
t = 4 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}=v_{o}+a*t[/tex]
where:
Vf = final velocity = 16 [m/s]
Vo = initial velocity = 0
a = acceleration = 4 [m/s²]
t = time [s]
Now replacing:
[tex]16=0+4*t\\t = 16/4\\t = 4[s][/tex]
why is it important to include variety in your workouts
Explanation:
Variety in to an exercise program allows the body to adapt to many demands, from high intensity exercise to slow, steady state exercise. Variety is important in a fitness program because it allows for your body to be challenged on a consistent basis and to overcome a plateau.
A particle is launched at an angle of 37° from horizontal. If the horizontal velocity component is 7.65 meters/second, what is the resultant velocity of the particle?
Answer:
R = 9.58 m/s
Explanation:
cos(37) = (7.65 m/s)/R
R = (7.65 m/s)/cos(37)
R = 9.58 m/s

Recall the formula,
∆θ = ω₀ t + 1/2 α t ²
where ∆θ = angular displacement, ω₀ = initial angular speed (which is zero because the disk starts at rest), α = angular acceleration, and t = time. Solve for the acceleration with the given information:
50 rad = 1/2 α (5 s)²
α = (100 rad) / (25 s²)
α = 4 rad/s²
Now find the angular speed ω after 3 s using the formula,
ω = ω₀ + α t
ω = (4 rad/s²) (3 s)
ω = 12 rad/s

How much resistance allows 6V battery to produce a current of 0.006 amps?
Answer:
It produces 1000Ω.
Explanation:
You have to apply Voltage formula, V = I × R :
V = I × R
6 = 0.006 × R
R = 6 ÷ 0.006
R = 1000Ω
We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms
From the Question we are told
How much resistance allows 6V battery to produce a current of 0.006 amps?
Generally the equation for Resistance mathematically given as
[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]
R=1000 ohms
Therefore
How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms

F = m x a. A ball of mass 0.35kg rolls on a smooth surface hits another object at rest and of mass 7kg. The second object gets an acceleration of 1.5m/s2. What acceleration does the ball get? Use newton’s third law.
Please show the working and thankyouu!!
Answer:
The acceleration the ball gets = 30 m/s²
Explanation:
The given parameters are;
The mass of the first ball that hits an object, m₁ = 0.35 kg
The mass of the object hit by the ball, m₂ = 7 kg
The acceleration given to the second object, a₂ = 1.5 m/s²
Let the a₁ represent the acceleration the ball gets
Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;
Therefore, we have;
The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N
The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁
By Newton's third law, F₁ = F₂, which gives;
m₁ × a₁ = m₂ × a₂
0.35 × a₁ = 10.5
a₁ = 10.5/0.35 = 30
The acceleration the ball gets = a₁ = 30 m/s².

how does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?
Answer:
F' = 9F
Explanation:
The electric force between charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
It means,
[tex]F\propto \dfrac{1}{r^2}[/tex]
If distance decreased by a factor of 3, r' = r/3
Net force will become,
[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\=9\dfrac{kq_1q_2}{r^2}\\\\=9\times F[/tex]
It means new force will become 9 times that of the initial force.
Answer:
it is increased by a factor of 9

John is a runner. He runs the 100m sprint in 10.6s. What speed did he travel at? (in m/s)
The answer you are looking for is approximately 9.4 m/s.
Solution/Explanation:
First, writing out the formula for the speed of an object, encompassing distance and time, in meters per second, or m/s,
S=D/T.
"S" stands for "Speed."
"D" stands for "Distance."
"T" stands for "Time."
Speed (S)=????
Distance (D)=100m.
Time (T)=10.6s.
Substituting the given values of the variables,
S=100m/10.6s.
100÷10.6=9.43396226415≈9.4.
So, therefore, the final answer is approximately 9.4 m/s.
