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

The peeled orange is much heavier than the water and hence it sinks and the whole orange is float as it is less denser than water.
The objects that float or sink depend on the buoyancy. Buoyancy is the tendency of the object to float in the liquids or fluids. When an object is immersed in a fluid, the object experience an upward force called buoyancy.
When the object sinks, its weight is less than the upward force or buoyancy. When the object floats, its weight is greater than the upward force.
The whole orange has a rind and the rind have tiny air pockets. When the orange is immersed in water, the water enters into the tiny air pockets and makes the orange less weight than the upward force and hence it floats.
When the rind is removed from the orange, the water can not enter the orange. Thus, the weight of the orange is greater than the upward force. Hence, it sinks.

a disk initially at rest rotates with constant angular acceleration through an angel of 50 rad in 5 sec find the angular speed of the disk just after 3 sec. please step by step
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

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]
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

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.
