Answer: 917
Explanation:
The change in momentum if a constant force of 917 N is exerted on a scooter for 6s is 5502kg-m/s.
How to calculate momentum?Momentum is the tendency of a body to maintain its inertial motion. It is the product of its mass and velocity, or the vector sum of the products of its masses and velocities.
Force = mass x (velocity/time)
Force = (mass x velocity)/time
Force = momentum/time
According to this question, a constant force of 917 N is exerted on a scooter for 6s. The change in momentum is calculated as follows:
917N = p/6
p = 5502kg-m/s
Therefore, 5502kg-m/s is the change in momentum of the scooter.

A 1200 kg car traveling at an unknown velocity has a rear-end collision with a 1600 kg car parked in the road. The cars lock bumpers and skid off together at 3.0 m/s. What was the velocity of the 1200 kg car right before the collision?
Answer:
Gotta be it
Explanation:
m1*v1 = m2*v2
1200*v1 = 1600*3
1200*v1 = 4800
v1 = 4800 / 1200
v1 = 4.0 m/s
calculate how much charge passes through the LED in 1 hour if the current flowing in the circuit below is 350mA
Given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.
What is Current?Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.
If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;
I = Q/t
Where Q is the charge and t is time elapsed.
Given the data in the question;
Time elapsed t = 1hr = 3600sCurrent I = 350mA = 0.35ACharge Q = ?We substitute our given values into the expression above to determine the charge.
I = Q/t
Q = I × t
Q = 0.35A × 3600s
Q = 1260C
Therefore, given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.

Why do the other bulbs go dark when one bulb is removed in the series circuit but the other bulbs do not go dark when one bulb is removed in the parallel circuit?
Answer:
I think this
One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function.
Consider an object of mass 2kg at rest on a ramp with βs=0.5 and βk=0.4.
If the ramp angle is 60 degrees, how far can the object travel in the first 1 seconds?
The distance traveled by the object in the first 1 second is determined as 0.98 m.
Distance traveled by the objectThe distance traveled by the object is calculated as follows;
F - μkmgcosθ = ma
0 - μkmgcosθ = ma
- μkgcosθ = a
-(0.4)(9.8)cos60 = a
- 1.96 m/s² = a
s = ut + ¹/₂at²
s = 0(1) + ¹/₂(-1.96)(1)²
s = -0.98 m
|s| = 0.98 m
Thus, the distance traveled by the object in the first 1 second is determined as 0.98 m.

If you wanted the laser to refract less as it exits the prism, you should increase the wavelength of the light.
What is refraction?Refraction can be defined as a phenomenon which describes a change (bend) in the path taken by light when it's at surfaces between different transparent materials.
According to the model of light wave, the refraction of light is inversely proportional to its wave. Thus, you should increase the wavelength of light, if you want the laser to refract less as it exits the prism.

Answer:
√ ae/ ap = √ mp/me 1/2
Explanation:
Mass of the electron = M (Given)
Mass of the proton = M (Given)
Time = t (Given)
Electrostatic force, FE = eE (for both electron and proton)But acceleration of electron, ae =FE/me whereas
acceleration of proton, ap = FE/mp
S = 1/2at²1 = 1/2apt²2
Therefore,t2/t1= √ ae/ ap
t2/t1= √ ae/ ap = √ mp/me 1/2
Thus, the ratio is nearly equal to = √ ae/ ap = √ mp/me 1/2so, option D is correctAnswer:
Correct option is D) …
Explanation:
For electron t1 (small 1) = [tex]\sqrt{ \frac{2S}{ae}[/tex] (small e)
For protion, t2 (small 2) = [tex]\sqrt \frac{2S}{ap}[/tex] (small p)
or [tex]\frac{t2}{t1}[/tex] = [tex]\sqrt\frac{ae}{ap}[/tex] = [tex]\sqrt\frac{eE}{me} *\frac{mp}{eE}[/tex]
= [tex]\sqrt\frac{mp}{me}[/tex]

A body of mass 200gram is executing SHM with amplitude of 20mm. The magnitude of maximum force which acts upon it is 0.6N. Calculate its maximum velocity?
Given ,
Mass of the body (m) = 200g
Amplitude (A) = 20mm
Maximum force (F) = 0.6 N
Maximum velocity (vmax) =?
We know that
Fmax = mv2max/A
or , 0.6 = 200×10-3xv2max/20×10-3
or , 0.6×20/200= v2max
or , vmax = 0.24 m/s
∴ Maximum velocity = 0.24 m/s2
The value of maximum velocity will be 0.3464 m/s². Energy or work is equal to the product of force and displacement.
What is velocity?The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.
The given data in the problem is
Mass of the body is,(m= 200g)
Amplitude is,(A =20 mm)
Maximum force is,F= 0.6 N
To find;
Maximum velocity
Energy or work is equal to the product of force and displacement.
[tex]\rm KE = \frac{1}{2} mV_{max}^2 \\\\ \rm F_{max} \times A = \frac{1}{2} mV_{max}^2 \\\\ F_{max}= \frac{1}{2}\frac{ mV_{max}^2}{A} \\\\ 0.6= \frac{1}{2}\times \frac{ 0.2 \times V_{max}^2}{20 \times 10^{-3}} \\\\ V_{max}=0.3464 \ m/sec^2[/tex]

what are the type of lens ?When a lens in the path of a beam of parallel rays causes the rays to diverge after refraction, it is referred to as a diverging lens.
It always creates a virtual image and has a thinner core than its boundaries.
Concave lenses(diverging lenses) function as diverging lenses because they cause light rays to diverge as they pass through them.
Therefore, when used with air as the operating medium, a concave lens can be thought of as a diverging lens.
The concave lens has several applications, including in telescopes, cameras, lasers, glasses, binoculars, and other optical devices.

A projectile is shot at initial speed v0 = 8.94 m/s with angle theta = 26.5 degree as shown. It reaches the distance x = 24 m.
Find height h of the cliff, your answer should be positive.
A projectile is shot with the initial speed, it follows the motion called projectile motion. The height of the cliff is 44.91 m.
What is initial speed?The speed at the start of the motion is the initial speed.
The horizontal distance is
x = v₀ sin θ. t
Substitute 26.5 for θ, 24 for x and 8.94 m/s for x, we get the time taken to complete the journey.
t = 24/ (8.94 cos26.5) = 3 s
Maximum height reached
H = v₀²sin²θ/2g
H = (8.94)² x sin²( 26.5) /(2 x 9.8)
H =0.8118 m
The height of the cliff is obtained by the equation of motion
0.8118 - h = -1/2 gt² +v₀sinθ.t
Substitute the values, we get
h =0.8118 +1/2x9.8x (3)²
h =44.911m
Thus, the height of the cliff is 44.91 m.

An object is being shot from a horizontal ground at an incline angle of 30 degree with respect to the ground at a speed of 52 m/s. Find the duration in seconds that the object is above the height of 14 m. Give your answer with one decimal place.
When an object is thrown at an angle from the horizontal, the path followed by the body is called the projectile motion. The duration in seconds that the object is above the height of 14 m is 4.698 s.
What is speed?Speed is the time rate at which velocity is changing.
Vertical speed component is
V₀y = 52sin 30°= 26 m/s
Given is the height h=14m
Using second equation of motion,
S=ut+ 1/2 at²
Substituting the values, we get
14 = 26t - 4.9t²
4.9t² - 26t +14 =0
Solving the quadratic equation, we get the time as
taking the positive sign, t =4.698 s
taking the negative sign , t = 0.6082 s
Thus, the duration in seconds that the object is above the height of 14 m is 4.698s.
