What is the velocity of a wave of frequency 200 Hz and wavelength 2 m?.
Answer:
[tex] \huge{\boxed{400 m/s}} [/tex]
Explanation:
The velocity of the wave given it's wavelength and frequency can be found by using the formula
[tex] \large{v = f \times \lambda}[/tex]
where
f is the frequency in Hz
[tex] \lambda [/tex] is the wavelength in m
From the question
f = 200 Hz
[tex] \lambda [/tex] = 2 m
We have
[tex] \large{v = 200 \times 2 = 400}[/tex]
We have the final answer as
400 m/sa ball attached to the end of a string is swung in a vertical circle. assuming the energy of the ball-earth system remains constant, show that the tension in the string at the bottom is larger than the tension in the string at the top by six times the weight of the ball.
The tension in the string at the bottom is larger than the tension in the string at the top by six times the weight of the ball as 4mg + 2mg = 6mg.
Calculate the tension in the spring?Let V₁ be the speed of ball at bottom and V₂ at top, If Ttop and Tbottom are tensions :-
According to conservation of energy;
1/2mv₁² = 1/2mv₂² + mg(2R)
m(v₁² - v₂²) = 4mgR
Tbottom = mv₁²/R + mg
Ttop = mv₂²/R - mg
Tbottom - Ttop = m/R(v₁² - v₂²) + 2mg
⇒ 4mg + 2mg = 6mg
What is tension?Any physical object that is in contact with another one can apply forces to that object. Depending on the types of objects in touch, we label these contact forces differently.

This idea can be used to show how variations in energy intake and expenditure will cause changes in body weight over time. Bodyweight is steady when the body is in a state of energy balance.
What is Equilibrium?
In physics, a system is said to be in equilibrium when neither its internal energy state nor its state of motion tend to vary over time. If a simple mechanical body experiences neither linear acceleration nor rotational acceleration, it is said to be in equilibrium.

What are the two heat sources of the interior of the Earth?.
The two primary sources of Heat in the Earth's interior are radioactive decay and primordial heat. Both of these sources of heat are essential for driving the Earth’s internal dynamics.
Radioactive decay is the process by which unstable, naturally-occurring elements such as uranium, thorium, and potassium decay into more stable elements. As these elements decay, they release energy in the form of heat. This energy is then transferred to the Earth’s interior, where it helps to drive convection in the mantle and other dynamics. This heat is also responsible for the generation of Earth’s magnetic field.
Primordial heat is heat that has been present within the Earth since its formation, and is thought to be a result of the kinetic energy of the Earth’s formation. This energy has been slowly released over time, and is currently estimated to contribute around 20% of the Earth’s total heat budget. This heat is also responsible for the generation of convection in the Earth’s mantle, and is one of the main drivers of plate tectonics and other Earth dynamics.

We are given the following Important parameters or information or data which is going to assist us in order to solve this question effectively and efficiently.
Jy = 500 Nm, Jb = 10 KNm, wy = 60 KN, wx = -80 KN.
Thus, I(bb) = 10/12 × 100 × (200 + 2 × 20)^3 - 1/2 (100 - 20) × 200^3.
l(bb) = 6.19 × 107 mm^4.
l(yy) = 1/12 × 20 × 240^3 × 2 + 1/2 × 200 × 20^3.
l(yy) = 4.62 × 10^7 mm^4.
Thus, the bending stress due to Jy = Jy × y / l(bb)
=> 500 × 10^ 3 × 0 /l(yy) = 0 MPa.
The bending stress due to Jb;
=> 500 × 10^ 6 ×( 200/2)/ 6.19 × 10^7 = 16.16 MPa.
The bending stress due to wx = wx/A= -80/800 = 10 MPa.
Transverse shear stress = 60 × 10^3 × 220000/ 6.19 × 10^ 7 × 20 = 10.66 MPa.
Principal stresses= T1 - T3/ 2 +/- ( T1 - T3/)^2 + c^2.

The medium adopts a shape as a result of the net impact of the two individual waves due to wave interference. Let's use the case of two pulses with the same amplitude moving in opposite directions through the same medium to better understand.
The dark bands, or fringes, represent the areas where the light waves from the diffraction grating have been cancelled out due to destructive interference.

ε = - π ( 0.12 )² ( ( 0.5 - 0 ) / ( 2 - 0 ) )
ε = - 1.1 * 10⁻² V
ε = - 0.011 mV
b ) For 2.0 s to 4.0 s,
ε = - π ( 0.12 )² ( ( 0.5 - 0.5 ) / ( 4 - 2 ) )
ε = 0
c ) For 4.0 s to 6.0 s,
ε = - π ( 0.12 )² ( ( 0 - 0.5 ) / ( 6 - 4 ) )
ε = 1.1 * 10⁻² V
ε = 0.011 mV
Therefore, the EMF induced in the loop during time intervals,
a ) 0 s to 2 s is - 0.011 mV
b ) 2 s to 4 s is 0
c ) 4 s to 6 s is 0.011 mV

To outside observers at rest, the overall sizes of objects traveling at relativistic speeds are.
The overall sizes of objects moving at relativistic speeds are smaller to observers outside the system who are at rest.
What is relativistic speeds?Relativistic speed is the rate at which relativistic effects are important for achieving the appropriate level of measurement precision for the event under study. The differences between values calculated by models that take relativity into account and those that do not are known as relativistic effects. This is approximately 186,282 miles per second, or "c," the equational symbol for light speed. Albert Einstein's special relativity theory, which is the cornerstone of much modern physics, states that nothing about the universe could move faster than light.
How do you calculate relativistic speed and is relativistic speed faster than light?Ek=mc21(v/c)2)mc2 is a formula for relativistic kinetic energy, where mm stands for rest mass, v for velocity, and c for the speed of light.
General Relativity, an idea first proposed by Albert Einstein, provides the basis for modern physics' understanding of spacetime. According to General Relativity, time and space are intertwined and nothing can move faster than the speed of light.

What is the slope of MN?.
Minnesota has a -3/4 slope is the slope of MN.
What angle of a line with a slope of 1 3 is perpendicular to it?What is the slope of a line parallel to one that has a slope of 1/3? Summary: A perpendicular line has a slope of -3 when the slope of the line is 1/3. When two lines are parallel, their slope product is negative one.
An opposing reciprocal slope will be present on a perpendicular line. To put it another way, the slope is reversed, and the sign is changed; as a result, the opposite reciprocal is 4/10.
In a plane, intersecting lines are those that cross one another three times or more.

projectile a is launched horizontally at a speed of 20 meters per second from the top of a cliff and strikes a level surface below. 3 seonds later projectile b launched horizontally from the same location at a speed of 30 meters per second. the time it takes projectile b to reach the level surface is
The time taken for projectile b to reach the level surface is 3 seconds.
Calculations:
According to the question;
Initial velocity = 0 m/s
Acceleration due to gravity = 9.81 m/s²
Time-taken for projectile A = 3s
Initial velocity of projectile B = 0 m/s
The height will be:
= 0.5 × a × t²
= 0.5 × 9.81 × 3²
= 44.145m.
The time is taken to projectile b:
44.145 = 0.5 × 9.81 × t²
t² = 44.145 / (0.5 × 9.81)
t² = 44.145 / 4.905
t² = 9
t = ✓9
t = 3 seconds

A ball is dropped onto the floor and bounces upward. Which of the following claims are correct about the force that the ball exerts on the floor compared to the force that the floor exerts on the ball when the ball and the floor are in contact?
The correct claim is "the force that the ball exerts on the floor and the force that the floor exerts on the ball when the ball and the floor are in contact are equal and opposite".
option D is the correct answer.
What is Newton's third law of motion?Newton's third law of motion states that for every action, there is an equal and opposite reaction.
According to this law, the force exerted on an object is equal to the reaction experienced by the object. In other words, action and reaction are always equal and opposite.
Mathematically, this law is written as;
Fa = Fb
where;
Fa is the force applied on the objectFb is the reaction exhibited by the object due to the applied forceFor a ball that is dropped onto the floor and bounces upward, the force that the ball exerts on the floor compared to the force that the floor exerts on the ball when the ball and the floor are in contact are equal and opposite.
Thus, we can conclude that the force exerted by ball on the floor and the reaction of the floor are equal and opposite.
