A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. At the moment contact is made with the battery, the voltage across the capacitor is:
a. greater than the battery's terminal voltage.
b. less than the battery's terminal voltage, but greater than zero.
c. zero.
d. equal to the battery's terminal voltage.
When contact is made with the battery, the voltage across the capacitor is zero.

What is the impulse needed to completely stop a 1300 kg car that's driving at 18
m/h?
Impulse needed to stop the 1300 kg car driving at a speed of 18 km/h or 5 m/s is 6500 kg m/s.
What is impulse?Impulse of a moving body is the change in its momentum. The ability to make the applied force increasing the displacement of a body is called its momentum. It is the product of mass and velocity of the body.
Impulse is the product of force and time. Here, the impulse we need to calculate is required to stop the car. Hence the final momentum is zero.
Given = 1300 kg
velocity = 18 km/h = 5 m/s
then initial momentum = 1300 kg × 5 m/s = 6500 kg m/s.
Final momentum = 0
thus, impulse = 6500 kg m/s - 0 = 6500 kg m/s
Therefore, the impulse of the car needed to stop it is 6500 kg m/s against the momentum.

A motorboat going downstream overcame a raft at a point A; Ï„=60min later it turned back and after some time the raft is at a distance l=6.0km from the point A. Find the flow velocity in km/h assuming the duty of the engine to be constant.
The flow velocity in km/h is 3 km/hr if the engine duty remains constant.
What is velocity?The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change.
Here,
Now, let's assume the velocity of boat to be v in still water.
While going down stream its velocity will be v + u
Velocity of boat relative to raft => v + u - u = + v after 1 hr distance between them will be v km.
In 1 hr raft moved by u× 1 = u km
Now while coming back
vb = -(v - u)
vr = + u
vb/r = - (v - u) - u = - v
So we see here that the relative velocity of boat with respect to raft is same as while going downstream or upstream both.
distance between them = v km.
So time in which they meet =
v/v=1 hr
So in next 1 hr they meet at some point,which will be 6 km away from A
Also in next 1 hr the raft would have traveled another u km. so total distance of meeting point from A in 2u = 6 ⇒ u = 3 km/hr
Flow velocity = speed of raft = 3 km/hr
The flow velocity in km/h assuming the duty of the engine to be constant is 3 km.

We know that,
the theorem states the relationship between work and energy. This theorem states that the change in kinetic energy is equal to the work
W = ΔKE = Force × displacement
Now given that,
Weight of the box, w = 80N
Length of the ramp, l = 20m
Angle, θ = 30⁰
Applied force on the box, F = 115N and
coefficient of the kinetic friction, μ = 0.22
first, we find the net force acting on the box
ΣF = Fsinθ - f
here, f is the frictional force
ΣF = Fsinθ - μwcosθ
or ΣF = 115(sin30°) - 0.22(80)cos30° = 115(0.5) - 17.6(0.86)
or ΣF = 42.26N
Now, by applying the work-energy theorem
W = ΣF×d = (42.26N)(20m) = 845.2J
Kinetic energy = 845.2J
Therefore, The box's kinetic energy is 845.2J when an 80.0 N box is pulled 20.0 m up a 30.0-degree ramp by a force of 115 N if the coefficient of kinetic friction between the box and the ramp is 0.22.

Enter a curve slower than the posted speed if your vehicle has a high center of gravity or if surface _____________ is less than ideal.
a. traction
b. speed
c. energy
d. maneuvers
a. traction
If your vehicle has a high center of gravity or if the surface traction is less than ideal, it is important to enter a curve slower than the posted speed. This is because vehicles with a high center of gravity or poor surface traction are more prone to instability and are more likely to roll over or lose control when negotiating sharp turns or curves at high speeds.
Traction refers to the friction or grip between the tires of a vehicle and the road surface. Poor surface traction can be caused by a variety of factors, such as wet or slippery roads, loose gravel or debris, or worn or damaged tires. When surface traction is poor, it becomes more difficult for the tires to maintain contact with the road and to transmit the forces of acceleration, braking, and steering to the road.
By entering a curve slower than the posted speed, you can reduce the lateral forces acting on your vehicle and give your tires more time to grip the road. This can help you maintain control and stability, and reduce the risk of accidents or injuries. It is important to always adjust your speed and driving style to suit the conditions of the road and the capabilities of your vehicle.

Based on the information provided, which of the following photosynthetic organisms can best absorb the wavelengths of light present at depths of 25 and 100 meters?
Photosynthetic organisms that best absorb the wavelengths of light at depths of 25 and 100 meters are organisms with chlorophyll A and phycoerythrin.
Photosynthesis is the process by which organisms use sunlight to create energy. Sunlight is necessary for photosynthesis to take place, but only some parts of the light spectrum are actually useful. Only the visible light range (blue to red) is considered active in photosynthesis.
Phycoerythrin is a type of light reflector commonly found in red algae and cyanobacteria. This means it can help reflect red light, which is important for seeing in low-light conditions.
Chlorophyll which is green blue will reflect green and absorb red, because the red color spectrum has a long wavelength, and the blue color spectrum has great energy.
Red light has a wavelength of 630 – 700 nm and green light has a wavelength of 480 – 560 n. So that organisms with chlorophyll A and phycoerythrin can live in the ocean at depths of up to 100 meters.
