the dependence of the rate constant on temperature is expressed by which equation?

Answer:

Explanation:

The formula for acceleration is:

a = (v_f - v_i) / t

Where:

a = acceleration

v_f = final velocity

v_i = initial velocity (in this case, 0 m/s since the car started from rest)

t = time

Plugging in the given values, we get:

a = (3600 m/s - 0 m/s) / 20 s

a = 180 m/s^2

Therefore, the acceleration of the car is 180 m/s^2.

Angular displacement is defined as “the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis”.

Formula:

S = rθ

∴ S = arc length

r = distance

θ = angular displacement

In physics, velocity and speed are similar but separate ideas. Speed, which is a scalar quantity, describes the extent of motion or the rate at which an item shifts in space.

A satellite is a body that orbits a planet, star, or moon. For instance, the fact that Earth orbits the sun makes it a satellite.

In physics, velocity and speed are similar but separate ideas. Speed, which is a scalar variable, describes the amount of motion or the rate at which an item shifts in space.

The satellite's speed, which is a scalar measurement of the magnitude of motion, is 100 m/s when it is moving in a circle.

However, because the satellite is moving in a circular path and its velocity has both a magnitude and a direction, it is continually varying.

The satellite's velocity is always moving in the direction of the circle's center, and its magnitude is equal to its speed, or 100 m/s.

Thus, this the comparison of satellites speed and velocity.

If the amplitude of the motion of a simple harmonic oscillator is doubled, the maximum speed of the oscillator increases by a factor of 2.

Here, we have a simple harmonic oscillator with an amplitude of let us say A. We know that the formula for speed of a Simple harmonic oscillator at any given point  is :

V = ω[tex]\sqrt{A^{2}-x^{2} }[/tex]

where, V = velocity , A is the amplitude , ω is the angular frequency of the motion and x is the position(displacement) of the oscillator.

We know that the maximum speed of the oscillator is at the mean or equilibrium point where  x = 0.

∴ Maximum velocity ⇒ ω[tex]\sqrt{A^{2} }[/tex]

⇒ Maximum Velocity = ωA

Now, doubling up the amplitude,

Maximum velocity when amplitude is doubled ⇒ ω[tex]\sqrt{(2A)^{2} }[/tex]

⇒ω[tex]\sqrt{4A^{2} }[/tex]

⇒2ωA

Now, dividing both the velocities ⇒(Maximum velocity when amplitude is doubled) / (First maximum velocity)

Explanation:

The electric flux through the loop is approximately 3.42 newton squared meters per coulomb (N·m^2/C).

The electric flux through a surface is given by the product of the electric field passing through the surface and the area of the surface,

Φ = EAcos(θ)

where Φ is the electric flux, E is the electric field, A is the area of the surface, and θ is the angle between the electric field and the normal to the surface.

In this problem, the electric field is parallel to the x-axis, so its angle with the normal to the circular loop is θ = 55°.

The area of the circular loop is A = πr^2, where r is the radius of the loop. Thus, the electric flux through the loop is:

Φ = EAcos(θ)

= (42 N/C)(π(0.24 m)^2)*cos(55°)

The force that occurs in a wooden block is the buoyant force on the block is greater when the block is completely submerged than it is when the block is floating.

So Archimedes' Law explains that there is a relationship between weight and upward force on a force if it is put in water. As a result of the upward lift (buoyancy), of course, objects that are in the liquid will experience a weight reduction. As a result, objects lifted in water will feel lighter than when lifted on land.

When submerged, the weight of the object in the liquid is greater than the upward force exerted by the liquid.

The tension needed to tune a grand piano string with a frequency of 27.5 Hz and a length of 1.90 m is 5,129 N.

The tension required to tune the string can be calculated using the following formula:

T = (mu * v^2) / L

Where T is the tension, mu is the string's linear mass density (mass per unit length), v is the wave's speed on the string, and L is the span of the string's vibrating portion.

To begin with, we must figure out the string's linear mass density:

mu = m/L = 0.440 kg/1.8 m = 0.2316 kg/m

The speed of the wave on the string needs to be calculated next. The equation: gives the speed of a wave on a string.

sqrt(T/u),

T represents tension, and u represents linear mass density. This equation can be changed to:

T = u

The tension required to tune the string can be calculated using the following formula:

T = (mu * v^2) / L

Where T is the tension, mu is the linear mass density of the string (mass per unit length), v is the speed of the wave on the string, and L is the length of the vibrating section of the string.

First, we need to calculate the linear mass density of the string:

mu = m / L = 0.440 kg / 1.90 m = 0.2316 kg/m

Next, we need to calculate the speed of the wave on the string. The speed of a wave on a string is given by the formula:

v = sqrt(T/u)

where T is the tension and u is the linear mass density. Rearranging this equation gives:

T = u * v^2

Substituting in the values we have:

v = f * lambda

where f is the frequency and lambda is the wavelength of the wave. The wavelength can be calculated from the length of the vibrating section of the string:

lambda = 2 * L = 3.80 m

Substituting in the values we have:

v = f * lambda = 27.5 Hz * 3.80 m = 104.5 m/s

Now we can calculate the tension:

T = u * v^2 / L = 0.2316 kg/m * (104.5 m/s)^2 / 1.90 m = 5,129 N

Therefore, the tension needed to tune this string properly is 5,129 N.

The force the pitcher exerts on the ball during this record-setting pitch is 160.15 N. The force exerted on the baseball as a fraction of the pitcher's weight is 0.195.

Concepts related to force include thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces changes in the rotational speed of an object. In an extended body, each part usually applies forces on the adjacent parts; the distribution of such forces through the body is internal mechanical stress.

The given parameters;

the initial velocity of the baseball, u = 47 m/s

distance traveled by the ball, d = 1 m

mass of the baseball, m = 145 g = 0.145 kg

The free-body diagram of the ball during the pitch is in the image added.

The acceleration of the baseball over the given distance is calculated as;

v² = u² - 2as

when the ball stops, the final velocity, v = 0

0 = u² - 2as

2as = u²

a= u²/2s

a = 1140.5 m/s²

The force the pitcher exerts on the ball during this record-setting pitch is calculated as;

F = ma

F = 0.145 x 1,104.5

F = 160.15 N.

The weight of the pitcher is calculated as;

W = mg

W = 84 x 9.8

W = 823.2 N

The force exerted on the baseball as a fraction of the pitcher's weight is calculated as follows;

True, if the electric flux through a closed surface is zero, the electric field at points on that surface must be zero.

What does a closed surface's electric flux look like?

The charge encapsulated divided by the permittivity is equal to the total electric flux out of a closed surface. The electric field is multiplied by the surface area projected in a plane perpendicular to the field to get the electric flux across a region.

If there is a net outward flow, the electric flux through a closed surface is positive; if there is a net inward flow, it is negative. If there is a source inside the closed surface, we have a net outward flux, and if there is a sink inside the closed surface, we have a net inward flux.

The complete question is: What points does King raise by juxtaposing opposites to highlight tension between what is and what should be?

The normal force of the bow on the string is 0.75 N. The coefficient of static friction between the bow and the string is 0.80. The string can be pulled before it slips if the string is bowed at its center as far as  106.06 m.

The maximum static friction force that can be applied to the string before it slips is the product of the normal force and the coefficient of static friction:

Fmax = μs × N = 0.80 × 0.75 N = 0.60 N

The tension in the string is 70 N. The string is bowed at its center, so the tension force is evenly distributed on both sides of the bow. The tension force on one side of the bow is:

Ft = 70 N / 2 = 35 N

The string will slip when the tension force exceeds the maximum static friction force:

Ft > Fmax

35 N > 0.60 N

The string can be pulled a distance of x before it slips. The tension force is equal to the product of the string's length and the distance the string is pulled:

Ft = L × x

35 N = 0.33 m × x

x = 35 N / 0.33 m = 106.06 m
