URGENT!!! sorry this is my first time using brainly! but here is my question: Two ropes are attached to a wagon, one horizontal

to the west with a tension force of 30 N, and the other east and at an angle of 30° northward and a tension force of 40 N. Find the components of the net force on the cart. Show all your work. Thank you in advance!

The components of the net force on the cart is determined as 67.66 N.

<h3>Component of net force on the cart</h3>

The component of net force on the cart is determined by resolving the forces into x and y -components.

T1 = 30 N

T2 = 40 N

T1x = -30cos(0) = 30 N

T1y = 30sin(0) = 0

T2x = 40 x cos(30) = 34.64 N

T2y = 40 x sin(3) = 20 N

∑X = 30 N + 34.64 N = 64.64 N

∑Y = 0 + 20 N = 20 N

<h3>Resultant force</h3>

R = √(64.64² + 20²)

R = 67.66 N

Which best describes the relationship between population size, carrying capacity, and limiting factors?
Alexandra [31]
When the sources is not enough for a population size that would limit population growth are limiting factors. And these limiting factors prevent the population size to increase. When it stops growing, the ecosystem reaches its carrying capacity. <span>Carrying capacity is the end of the line of a population size that the ecosystem can support over time.</span>

A 763 kg car moving at 26 m/s brakes to a stop. The brakes contain about 15 kg of iron that absorb the energy. What is increase
Neko [114]

Answer:

\Delta T=38.20^{\circ}

Explanation:

It is given that,

Mass of the car, m = 763 kg

Speed of the car, v = 26 m/s

Mass of the iron, m' = 15 kg

Specific heat of iron, c = 450 J/kg

When the car is in motion, it will possess kinetic energy. It is given by :

K=\dfrac{1}{2}mv^2

K=\dfrac{1}{2}\times 763\times (26)^2

K = 257894 J

Since, energy is absorbed by the brakes. The kinetic energy of the car is absorbed by the brakes. So,

K=mc\Delta T

\Delta T is the increase in temperature of the brakes

\Delta T=\dfrac{K}{m'c}

\Delta T=\dfrac{257894}{15\times 450}

\Delta T=38.20^{\circ}

So, the increase in temperature of the brakes is 38.20 degrees Celsius. Hence, this is the required solution.

If a car that is moving 20.0 m/s has a momentum of 29000 kg·m/s, what mass is the car?
Strike441 [17]

Answer:

Mass = 1450kg

Explanation:

P = M * V (where p is momentum, m is mass and v is velocity)

29000 = 20 * M

M = 29000 / 20

M= 1450 kg

Which of the following safety devices provides a weak link in a circuit that will melt if it received too much current, thus bre
SVETLANKA909090 [29]
The correct answer is B. Fuse.

Fuses were commonly used in houses up to recent ages, when circuit breakers became the more popular options, as they don't have to be changed every time they melt, since they don't melt.

It is 5.0 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h
Ostrovityanka [42]

Answer:

Walking burns up more energy,1740000J

Explanation:

Given that the displacement is 5.0km, and running at 10km/h and uses, walking at 3km/hr and uses 290watts:

Energy consumption for running is calculated as:

700watts=700j/s,d=5000m,v=\frac{25}{9}m/s\\\\\therefore E_c=\frac{d}{v}\times Energy \ usage\\\\=\frac{5000}{\frac{25}{9}}\times 700j/s\\\\=1260000J

Energy consumption for walking is calculated as:

290watts=290j/s,d=5000m,v=\frac{5}{6}m/s\\\\\therefore E_c=\frac{d}{v}\times Energy \ usage\\\\=\frac{5000}{\frac{5}{6}}\times 290j/s\\\\=1740000J

Walking is a slower process hence the need for more energy over longer periods  raltive to running the same distance.

Hence walking burns more energy; 1,740,000J. It burns more because you walk for a greater period of time.
