A 1000 kg car rides over a hill with a radius of curvature of 30 m. What is the maximum speed that the car can
travel over the hill without launching off the hill (when it's too fast to be in circular motion). Round to a whole
number.
Let's say that the car moves over the hill at 10m/s. What is the value of the normal force at the top of the hill? Answer with 2 sig figs
Answer:
hi-
Explanation:
Since v = R , For the car to lose contact with the road, it must be traveling at a speed of 28 m/s or greater when it reaches the crest of the hill. At lower speeds, the car would remain in contact with the road.
how much work was done on a charge of 3.0 to move it through 12v electric potential difference
Answer:
Hence, the work done in moving the charge is 45 J.( Too lazy to translate it to Spanish T_T )Answer:
45 J
Explanation:
Potential difference (V)= 15 V
Charge (Q)= 3C
We know that
The potential difference(p.d) between two point in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point.
Potential difference (V) = work done (W)/Charge (Q)
V= W/Q
Putting the values in the above formula we get:
15 V = W / 3 C
W= 15 V × 3 C
W= 45 J
Hence, the work done in moving the charge is 45 J.
Light incident on a lake surface is partly reflected and partly refracted. How is the reflected ray different from the incident ray? A. The incident ray is unpolarized whereas the reflected ray is horizontally polarized. B. The incident ray is unpolarized whereas the reflected ray is vertically polarized. C. The incident ray is horizontally polarized whereas the reflected ray is unpolarized. D. The incident ray is vertically polarized whereas the reflected ray is unpolarized. E. The incident ray is vertically polarized whereas the reflected ray is horizontally polarized.
Option B is correct.
(B )The incident ray is unpolarized whereas the reflected ray is vertically polarized.
What is a ray?Ray is the next in a series of characters. Ray is made up of two elements: a line and a line segment. It has one terminating end and one indefinitely extending end.
The ray's length cannot be determined. A ray is seen in the diagram below.
Reason ;
Many light sources, such as the sun, create polarised waves ( randomly). Unpolarized light is made up of a large number of waves with all conceivable polarisation directions.
Hence option B is correct.
(B )The incident ray is unpolarized whereas the reflected ray is vertically polarized.

Find the Thrust required to exert a Pressure of 80000 Pascal on an Area of 0.04 m²
Question :-
Find the Thrust required to exert a Pressure of 80000 Pascal on an Area of 0.04 m² .Answer :-
The required Thrust is 3200 N .[tex] \rule {180pt} {2pt} [/tex]
Given :-
Pressure = 80000 PascalArea = 0.04 m²To Find :-
Thrust = ?Solution :-
As per the provided information in the given question, we have been given that the Pressure is 80,000 Pascal . Area is given 0.04 m² . And, we have been asked to calculate the Thrust .
For calculating the Thrust , we will use the Formula :-
Thrust = Pressure × AreaTherefore , by Substituting the given values in the above Formula :-
⇒ Thrust = Pressure × Area
⇒ Thrust = 80000 × 0.04
⇒ Thrust = 3200
Hence :-
Thrust = 3200 N .[tex] \underline {\rule {180pt} {4pt}} [/tex]
Provided that:
Pressure = 80,000 PascalArea = 0.04 m sq.To determine:

During early research in nuclear energy, why were scientists surprised that the products from splitting a uranium nucleus had less mass than the reactants? They expected that the large release of energy would cause an increase in mass. Up to that time, only chemical changes were known to form less mass than they started with. All known changes always started and ended with the same amount of mass. Other known nuclear changes resulted in the same mass of products as reactants.
The scientist gets surprised In terms of the masses of the subatomic particles, scientists anticipated the rule of conservation of mass to apply to nuclear fission and it got failed.
What is nuclear power?The utilization of nuclear reactions to generate energy is known as a nuclear power. Nuclear fission, nuclear decay, and nuclear fusion processes are all sources of nuclear energy.
Nuclear power facilities currently produce the great bulk of the electricity generated by nuclear fission of uranium and plutonium.
In terms of the masses of the subatomic particles, scientists anticipated the rule of conservation of mass to apply to nuclear fission.
An atom's mass is not equal to the sum of the masses of the subatomic particles that make it up in actuality.
The energy that bonds the subatomic particles is the reason behind this. When a link is broken, the mass of the energy of the bonds is lost, resulting in what we now refer to as a mass defect.

Why MA Is less than VR?
The mechanical advantage (M.A) of a real

because mechanical advantage decreases due to the friction and weight of moving parts of the machine where as the velocity ratio remains constant.

A positive test charge of 5.0x10 -6 C is in an electric field that exerts a force of 2.0x10 -4 N on it. What is the magnitude of the electric field at the location of the test charge
answer:
click on the picture, hope it helps
The magnitude of the electric field at that location is is 40 N.C⁻¹.
What is electric field?The force per unit charge exerted on a positive test charge that is at rest at a given position is the force per unit charge that is used to define the electric field analytically.
Electric charge or magnetic fields with variable amplitudes can produce an electric field.
Given parameters:
Charge of the positive test charge, q = 5.0x10⁻⁶ C.
Electric force exerted by the electric field, F = 2.0x10⁻⁴ N.
Then, electric field at the position, E = F/q
= 2.0x10⁻⁴ / 5.0x10⁻⁶ N.C⁻¹.
= 40 N.C⁻¹.
Hence, the magnitude of the electric field at the location of the test charge is 40 N.C⁻¹.
