a typical 100-watt light bulb consumes 100 j of energy per second. if a light bulb converts all of this energy to 400 nm light, how many photons are produced each second?
Answer:
Let y equal lambda the wavelength of the light
e (photon) = h f = h c / y
e = 6.63E-34 * 3.0E8 / 400E-9
e = 6.63 * 3 / 400 * 10^-17
e = 4.97E-19
N= 100 J/sec/ 4.97E-19 J = 2.01E20 / sec

Write down the relation between force pressure and area
Answer:
Answer: Pressure is directly proportional to force and inversely proportional to area.
Explanation: Pressure is defined as the ratio of force applied to the area of cross section.
Mathematically,
P=\frac{F}{A}P=
A
F
where,
P = Pressure
F = Force applied
A = Area of cross-section
from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.
The units of pressure are N/m^2N/m

and S.I. units for this term is Pascal (P).

If you push on a cart, the force of friction will slow it down. Friction is the conversion of kinetic energy to __________ .
Answer:thermal energy
Explanation:The friction converts kinetic energy to thermal energy (heat). When two objects are in contact, friction will act with these two objects so this...
Answer:
Heat
Explanation:
Friction always slows a moving object down. ... Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.

Two balls are dropped from rest and allowed to fall. If one ball is allowed to fall for 1 s and the other for 3 s compare the distances they have fallen.
The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.
The given parameters;
time of fall of the first ball, t = 1 stime of fall of the second ball, t = 3 sThe distance traveled by each ball is calculated using the second equation of motion as shown below.
The distance traveled by the first ball is calculated as follows;
[tex]h = u_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 1^2)\\\\h = 4.9 \ m[/tex]
The distance traveled by the second ball is calculated as follows;
[tex]h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 3^2)\\\\h = 44.1\ m[/tex]
Thus, the second ball traveled a greater distance because it spent more time in motion.

A Yugo can accelerate from rest to a speed of 28 m/s in 20 s. What is the average acceleration of the car? What distance does it travel in this time
Answer:
Explanation:
a=28/20
a=1.4 m/s²
V²=v0²+2a.D
28²=0+2x1.4D
784 = 2.8D
D = 280 m
uses of concave and convex mirror
hello?
Explanation:
→ Uses of Convex Mirror
• Convex mirrors are often used in the hallways of buildings including stores, schools, hospitals, hotels and apartment buildings.
• They are used in driveways, roads, and alleys to provide safety to all the bikers and motorists at curves and turns and other places where there is a lack of visibility.
• They are also used in some automated teller machines as a handy security feature that allow user to see what all is happening behind them.
• They are used in passenger side mirror on a car and somewhere it is labelled as “objects in mirror are closer than they appear” to warn the driver.
→ Uses of concave mirror :
• Head mirrors
• Shaving mirrors
• Headlights
• Ophthalmoscope (optical instrument)
• Solar furnaces
• Astronomical telescopes
11. A roller coaster car is moving slowly up a long ramp to the very top of the roller coaster. It goes over the top and starts down a steep slope and it picks up speed rapidly as it rolls down an almost vertical slope. Four seconds later, at the bottom of the steep slope, its velocity is 28 m/s. The average acceleration during those 4 seconds was 6 m/s2 . What was the initial velocity of the roller coaster car as it started down the slope?
Answer:
a = (v2 - v1) / t
a t = v2 - v1
v1 = v2 - a t
v1 = 28 m/s - 6 m/s^2 * 4 s = 4 m/s
state the general relationship between temperature and water depth.
Answer:
Temperature decreases as depth increases (generally)
Explanation:
In general, sunlight will heat the upper level of water. As you go deeper into the water, the sunlight cannot reach as easily so the temperature is lower.
There are exceptions considering underwater currents like the Gulf Stream or volcanic vents.

Answer:

Explanation:

The pressure due to water at the bottom of the tank is 200000 Pascal.
What is pressure?It is the ratio between the force being applied and the surface area being applied to. The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure.
Given parameters:
Depth of the tank = 25 meter.
Depth of water in the tank: d = 25×4/5 meter = 20 meter.
Density of water: ρ = 1000 kg/m³.
Acceleration due to gravity: g = 10 m/s².
Hence, the pressure due to water at the bottom of the tank
= depth of water (d) × density of water (ρ) × acceleration of the gravity (g)
= 20 meter × 1000 kg/m³ × 10 m/s²
= 200000 Newton/meter²
=200000 Pascal.
Hence, the pressure due to water at the bottom of the tank is 200000 Pascal.

A hammer falls from a construction worker's hand 30m above the ground at the same time that a filled soft drink can is projected vertically upward from the ground at a velocity of 24 m/s. Where and when will the two objects meet?
For harmer:-
initial velocity=u=0m/sAcceleration due to gravity=10m/s^2Now
[tex]\\ \sf\longmapsto s=ut+\dfrac{1}{2}gt^2[/tex]
[tex]\\ \sf\longmapsto s=0t+\dfrac{1}{2}(10)t^2[/tex]
[tex]\\ \sf\longmapsto s=5t^2\dots(1)[/tex]
For soft drink:-
u=24m/s[tex]\\ \sf\longmapsto 30-s=(24)t+\dfrac{1}{2}(10)t^2[/tex]
Using eq(1)[tex]\\ \sf\longmapsto 30-5t^2=24t-5t^2[/tex]
[tex]\\ \sf\longmapsto 24t=30[/tex]
[tex]\\ \sf\longmapsto t=\dfrac{30}{24}[/tex]

After 1.2s they will meet.Now
putting t in eq(1)
