An incident light ray hits a plane surface at 20 degrees (hint: remember where the angle is measured from). What is the angle between the incident and reflected rays? So is it 20 degrees or 40 degrees
Answers
Answer:
[tex]40^{\circ}[/tex]
Explanation:
The incident angle is [tex]20^{\circ}[/tex] so the reflected ray will also be [tex]20^{\circ}[/tex].
The normal divides the angle between the incident and reflected ray. So, the angle between them would be
[tex]\text{Incident angle}+\text{Reflected angle}=20+20=40^{\circ}[/tex]
So, the angle between the incident and reflected rays is [tex]40^{\circ}[/tex].

A new piece of exercise equipment has been added to your gym, and you try it out. To use this machine, you lie horizontal on a mat with your feet against a platform perpendicular to the mat. The platform is held by a stiff spring that is compressed when the platform moves. Your workout invovles compressing the spring by pushing on the platform with your feet. After testing compressions of the equipment, you determine that you must do 85.0 J of work to compress the spring a distance 0.170 m from its uncompressed length.What magnitude of force must you apply to hold the platform stationary at the final distance given above
Answers
Answer:
500 N
Explanation:
Since the work done on the spring W = Fx where F = force applied and x = compression length = 0.170 m (since the spring will be compressed its full length when the force is applied)
Since W = 85.0 J and we need to find F,
F = W/x
= 85.0 J/0.170 m
= 500 N
So, the magnitude of force must you apply to hold the platform stationary at the final distance given above is 500 N.
Un auto de 1000 kg que lleva una velocidad de 72 km/h se detiene en una distancia de 100 metros cuando se le aplican los frenos. (a) ¿Cuál es la fuerza constante producida por los fre. Nos? (b) Con esta fuerza, ¿cuál seria la distancia de frena do si la velocidad hubiera sido de 36 km/h?
Answers
Answer:
a) F = 2000 N , B) x = 25 m
Explanation:
a) To solve this exercise we can use the relationship between work and kinetic energy
W = ΔK
The job is
W = -F x
the negative sign is because the force of the brakes is contrary to the movement
as the car stops its final kinetic energy is zero
K = ½ m v²
let's substitute
- F x = 0 - ½ m v²
F = ½ m v² / x
Let's reduce the magnitudes to the SI system
v = 72 km / h (1000m / 1km) (1 h / 3600 s) = 20 m / s
let's calculate
F = ½ 1000 20²/100
F = 2000 N
b) x = ½ mv2 / F
let's slow down to the SI system
v = 36 km / h = 10 m / s
let's calculate
x = ½ 1000 10²/2000
x = 25 m

Kyle and Jenny both have pet rabbits. They wanted to see who had the fastest rabbit, so they each recorded data at their homes and brought it's the results. Kyle rabbit went a total of 40 m in a time of one minute and 20 seconds. Jenny's rabbit went 30 m in one minute and 30 seconds. What was the velocity of Kyle's rabbit? What was the velocity of jennies rabbit? Whose rabbit was the fastest?
Answers
Answer:
v_kyle = 0.5 m/s
v_jennies = 0.333 m/s
Kyle's Rabbit was the fastest
Explanation:
For the velocity of Kyle's Rabbit:
d = distance covered = 40 m
t = time taken = (1 min)(60s/1 min) + 20 s = 80 s
[tex]v_{kyle} = \frac{d}{t} = \frac{40\ m}{80\ s}[/tex]
v_kyle = 0.5 m/s
For the velocity of Jennies Rabbit:
d = distance covered = 30 m
t = time taken = (1 min)(60s/1 min) + 30 s = 90 s
[tex]v_{jennies} = \frac{d}{t} = \frac{30\ m}{90\ s}[/tex]
v_jennies = 0.333 m/s
It is clear from the results that:
Kyle's Rabbit was the fastest

The cornering performance of an automobile is evaluated on a skid pad, where the maximum speed that a car can maintain around a circular path on a dry, flat surface is measured. Then the centripetal acceleration, also called the lateral acceleration, is calculated as a multiple of the free-fall acceleration g. The main factors affecting the performance of the car are its tire characteristics and suspension system. A Dodge Viper GTS can negotiate a skid pad of radius 61.0 m at 86.5 km/h. Calculate its maximum lateral acceleration.
Answers
Answer:
0.04g
Explanation:
Since it lateral acceleration is is its centripetal acceleration, the centripetal acceleration, a is given by
a = v²/r where v = speed of Dodge Viper GTS= 86.5 km/h = 86.5 × 1000 m/3600 s = 24.03 m/s and r = radius of skid pad = 61.0 m.
So, a = v²/r
= 24.028 m/s ÷ 61.0 m
= 0.394 m/s²
So, its maximum lateral acceleration is 0.394 m/s². Since g = acceleration due to gravity = 9.8 m/s²
a/g = 0.394 m/s² ÷ 9.8 m/s² = 0.04
So, a = 0.0402g
a ≅ 0.04g

Q: You're playing a game of catch with a dog, the dog is initially standing near your feet. Then he jogs 20ft in a straight line to retrieve the stick and carries the stick 15ft back towards you before lying on the ground to chew the stick.
A). Cal the total distance
B) . Total displacement
C). Show that the net displacement of the trip is the sum of the sequential displacement that makes up the trip.
Answers
Answer:
A) 35 ft
B) 5 ft
C) Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick
Explanation:
A) Total distance covered by the dog = 20 + 15
= 35 ft
B) Since the other distance covered by the dog before chewing the stick, after the retrieval, was in an opposite direction to the initial direction, then;
total displacement of the dog = 20 - 15
= 5 ft
C) Net displacement = distance covered by the dog to retrieve the stick + distance covered before the dog starts chewing the stick
But, displacement involves a specified direction. The distance covered before the dog starts chewing the stick was in an opposite direction to the initial direction.
Thus,
Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick

A rectangular container of base 50 cm by 30 cm is filled with water to a depth of 5 cm. How much is the pressure exerted at the base? (Take p= 1000 kg/m3 and g=10m/s)
Answers
Answer:
the pressure exerted at the base of the container is 490 N/m²
Explanation:
Given;
density of water, ρ = 1,000 kg/m³
base of the rectangular container, = 50 cm by 30 cm
height of water in the tank, h = 5 cm = 0.05 m
The pressure exerted at the base of the container is calculated as;
P = ρgh
where;
g is acceleration due to gravity = 9.8 m/s²
P = 1000 x 9.8 x 0.05
P = 490 N/m²
Therefore, the pressure exerted at the base of the container is 490 N/m²

Heat capacity is given by the formula;
[tex] Q = mct[/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.

Which is the right answer
A
B
C or
D
Answers
Answer:
B
Explanation:
Density=mass/volume
Density=8.5g/17mL
Density=0.5 g/mL
An object has a mass of 8.5 g and a volume of 17 mL, then the density will be 0.5 g/mL. The correct option is b.
The density of matter is a physical quantity that indicates how much mass is contained within a particular volume.
It is defined as a substance's mass per unit volume. In other words, density quantifies how tightly packed a substance's particles are.
We know that:
Density = Mass / Volume
Density = 8.5 g / 17 mL
Simplifying the calculation:
Density = 0.5 g/mL
Therefore, the density of the object is 0.5 g/mL. So, the correct answer is option b. 0.5 g/mL.
