Answer:

It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. Samaira needs to rent some tents for an outdoor family reunion in July, so the type of tent for Samaira to rent so that her family members are protected from the heat of the sun is SMOOTH and WHITE TENT. Hope this answer helps.

If Samaira wants to protect her family members from the heat of the sun during their outdoor reunion in July, she should consider renting a white color tent that provides shade and ventilation.

Brighter colors reflect more light than darker colors, yet darker colors actually absorb more light. Light is absorbed more effectively by darker colors. Since light is energy, absorption would raise the temperature of a substance.

A good option would be a canopy tent or a shade tent, which are designed to provide shade and protection from the sun's UV rays.

Another important feature to consider is ventilation. Tents with mesh walls or windows allow for airflow, which can help keep the interior of the tent cool and comfortable.

Thus, Samaira should look for a white color tent with a high UPF rating, ventilation, and an appropriate size for her family reunion.

Answer:

Δλ = 3*10⁻³ m.

Explanation:

       \(v = \lambda* f (1)\)

       where v is the speed, λ is the wavelength and f is the frequency.

       \(\lambda = \frac{v}{f} (2)\)

        \(\lambda_{1} =\frac{v}{f_{1}} = \frac{343m/s}{440(1/s)} = 0.779 m (3)\)

Answer:

2. decreasing the distance of the space shuttle from Earth

Explanation:

To increase the gravitational force on a space shuttle, it is a good thing to decrease the distance of the space shuttle from the earth.

This is based on the Newton's law of universal gravitation which states that "the gravitational force between two bodies is a directly proportional to the product of their masses and inversely proportional to the square of the distance between them".

 Mathematically;

           F  = \(\frac{G m_{1} m_{2} }{r^{2} }\)  

G is the universal gravitation constant, it cannot be changed

m is the mass of the body

r is the distance

  Since the distance is inversely proportional, is we reduce it, the value of the gravitational force will increase.

Answer:

The answer is B

Explanation:

took the exam

The spring constant k based on the information is 12.0 N/m.

From the information, a spring stretches 0.294-m when a 0.360-kg mass is gently suspended from it as in Fig. 11–3b. The spring is then set up horizontally with the 0.431-kg mass resting on a frictionless table.

The spring constant k is the force required to stretch or compress the spring by a unit distance. In this case, the spring is stretched by 0.294 m when a 0.360 kg mass is suspended from it.

This means that the force exerted by the spring is equal to the weight of the mass, which is 0.360 kg x 9.8 m/s^2 = 3.53 N.

Therefore, the spring constant k is:

= 3.53 N/0.294 m

= 12.0 N/m.

If the impulse is strong enough and lasts for a sufficient amount of time, the go-kart will eventually come to a stop.

Option A is correct.

impulse is described as the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity.

If the force is insufficient to stop the go-kart entirely, it will slow down but continue to move. The force and duration of the impulse, along with the mass and speed of the go-kart, will all affect how much deceleration occurs.

Given that momentum plus impulse equals zero, the go-kart's change in momentum as a result of the impulse will be equal in amount but will move in the opposite direction of its original momentum.

As a result, the go-kart's final momentum will be zero, suggesting that it has either stopped or is travelling very slowly.

Answer:

Option C

Explanation:

Frequency determines the number of waves that pass through any defined point in a given time period.

Frequency of 1 hertz means that one wave travels through a given point in one second.

By the above definition, we can say

The energy stored in the circuit at any time t is given by \(U = (1/2)L*I^{2} + (1/2)Q^{2} /C = (1/2)L*(V_{0} /R)^{2} *e^{(-2t/(R*C))} + (1/2)C*V_{0} ^{2} *(1 - e^{(-2t/(R*C)})).\)The units are in seconds.

The total energy stored in the circuit can be calculated using the formula: U = (1/2)L*I² + (1/2)Q²/C, where L is the inductance, I is the current, Q is the charge on the capacitor, and C is the capacitance.

Initially, the capacitor is uncharged, so the second term is zero.

Therefore, the initial energy stored in the circuit is U₀ = (1/2)L*I₀², where I₀ is the initial current, which is zero.

When the magnetic field is switched on, a current begins to flow in the solenoid.

This current increases until it reaches its maximum value, given by I = V/R, where V is the voltage across the solenoid and R is its resistance.

Since the solenoid is connected in series with the capacitor, the voltage across the solenoid is equal to the voltage across the capacitor, which is given by V = Q/C, where Q is the charge on the capacitor.

The charge on the capacitor is given by Q = C*V, where V is the voltage across the capacitor at any time t.

Therefore, we have I = V/R = Q/(R*C) = dQ/dt*(1/R*C), where dQ/dt is the rate of change of charge on the capacitor.

This is a first-order linear differential equation, which can be solved to give \(Q(t) = Q_{0} *(1 - e^{(-t/(R*C)}))\), where Q₀ is the maximum charge on the capacitor, given by Q₀ = C*V₀, where V₀ is the voltage across the capacitor at t=0.

The current in the solenoid is given by I(t) = \(dQ/dt*(1/R*C) = (V_{0} /R)*e^{(-t/(R*C)}).\)

The energy stored in the circuit at any time t is given by\(U = (1/2)L*I^{2} + (1/2)Q^{2} /C = (1/2)L*(V_{0} /R)^{2} *e^{(-2t/(R*C))} + (1/2)C*V_{0} ^{2} *(1 - e^{(-2t/(R*C)})).\)

The time t at which the energy stored in the circuit drops to 10% of its initial value can be found by solving the equation U(t) = U₀/10, or equivalently, \((1/2)L*(V_{0} /R)^{2} *e^{(-2t/(R*C)}) + (1/2)C*V_{0} /R)^{2}*(1 - e^{(-2t/(R*C)})) = (1/20)L*I_{0} /R)^{2}.\)

This equation can be solved numerically using a computer program, or graphically by plotting U(t) and U₀/10 versus t on the same axes and finding their intersection point.

The solution is t = 1.74 ms.

The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 degree celsius. The formula for calculating the heat is expressed as

H = mcθ

where

θ is the change in temperature(final temperature - initial temperature)

m is the mass of the substance in kg

c is the specific heat capacity

From the information given,

initial temperature = 22.3

final temperature = 31

θ = 31 - 22.3 = 8.7

m = 125g

We would convert 125g to kg

recall, 1 kg = 1000g

125g = 125/1000 = 0.125kg

c = 2.42

H = 0.125 x 2.42 x 8.7

H = 2.63J

To find the mass in kilograms, you need to know the object's weight in newtons and the acceleration due to gravity. The formula for finding mass is mass = weight / acceleration due to gravity. So if you have an object with a weight of 100 N and the acceleration due to gravity is 9.8 m/s^2, the mass would be 10.204 kg.

Answer:

Resultant displacement = 1222.3 m

Angle is 88.3 degree from +X axis.

Explanation:

A = 550 m north

B = 500 m north east

C = 450 m north west

Write in the vector form

A = 550 j

B = 500 (cos 45 i + sin 45 j ) = 353.6 i + 353.6 j

C = 450 ( - cos 45 i + sin 45 j ) = - 318.2 i + 318.2 j

Net displacement is given by

R = (353.6 - 318.2) i + (550 + 353.6 + 318.2) j

R = 35.4 i + 1221.8 j

The magnitude is

\(R = \sqrt{35.4^{2}+1221.8^{2}}R = 1222.3 m\)

The direction is given by

\(tan\theta =\frac{1221.8}{35.4}\\\\\theta = 88.3^{o}\)

The average velocity of the particle between t = 2.0 s and t = 4.0 s is 4 m/2.0 s = 2.0 m/s.

Average velocity is the rate of change of an object's position, expressed as a vector quantity that tells both the speed and direction of the object's motion.

The average velocity of the particle between t = 2.0 s and t = 4.0 s can be calculated by taking the difference in the x-position of the particle at t = 4.0 s and t = 2.0 s, and dividing it by the difference in the time.
The x-position of the particle at t = 2.0 s is 4 m and the x-position of the particle at t = 4.0 s is 8 m.
Therefore, the difference in the x-position is 8 m - 4 m = 4 m.
The difference in time is 4.0 s - 2.0 s = 2.0 s. Therefore, the average velocity of the particle between t = 2.0 s and t = 4.0 s is 4 m/2.0 s = 2.0 m/s.
