Juanita, en medio de la cuarentena tuvo que salir de su casa por algunos artículos que necesitaba; utilizó su tapabocas y guantes, salió corriendo con velocidad de 3m/s a comprar, 3 kilogramos de arroz, dos litros de leche y 5 tapabocas. Para completar el total de las cosas, primero debe ir al supermercado que esta ubicado a 50 metros, en dirección 30 grados con respecto a la horizontal partiendo desde su casa, y de allí, salir para la droguería que se encuentra ubicada a 70 metros, dirección 150 grados desde el supermercado geográficamente con respecto a la horizontal. 1. Clasifique las cantidades escalares y las cantidades vectoriales del problema

Answers

Answer 1
Answer:

Answer:

the scalar quantities in this exercise are: 3 kg rice, 2 liters of milk and 5 face masks, the rapides 3 m / s

the vector quantities are: the displacement to the supermarket  and   the  drugstore

Explanation:

For this problem we are asked to find scalar quantities and vector quantities.

A scalar quantity is one that is described by a number with its units

A vector quantity is that described by a number (module), a direction and a sense, that is, they must be represented by a vector

the scalar quantities in this exercise are: 3 kg rice, 2 liters of milk and 5 face masks, the rapides 3 m / s

the vector quantities are: the displacement to the supermarket module 50 m directional 30º sense with respect to the horizontal.

The displacement to the drugstore modulo 70 m direction 150º with respect to the supermarket

A very small 100-g object is attached to one end of a massless 10-cm rod that is pivoted without friction about the opposite end. The rod is held vertical, with the object at the top, and released, allowing the rod to swing. What is the speed of the object at the instant that the rod is horizontal?

Answers

Answer:

1.40071 m/s

Explanation:

m = Mass of object = 100 g

v = Velocity of object

h = Height of drop = 10 cm

g = Acceleration due to gravity = 9.81 m/s²

Here, the loss of potential energy is equal to the gain in kinetic energy as energy is conserved

mgh=(1)/(2)mv^2\n\Rightarrow gh=(1)/(2)v^2\n\Rightarrow v^2=2gh\n\Rightarrow v=√(2gh)\n\Rightarrow v=√(2* 9.81* 0.1)\n\Rightarrow v=1.40071\ m/s

The speed of the object at the instant that the rod is horizontal is 1.40071 m/s

Which of the following is NOT an early sign of heat illness?Dizziness
Headache
Flushed face
Excessive sweating
Struggling to perform

Answers

Struggling to perform is not an early sign of heat illnesses.

There are times when the body system will be unable to dissipate heat effectively. When this happens, heat illness bounds to occur.

Also, heat illnesses tend to occur when the balance of salt and water in the body becomes unbalanced, the temperature rises unexpectedly or the sweet couldn't keep an individual cool.

Some of the early signs includes Headache, dizziness, Muscle cramps, weak pulse among other related symptoms.

Based on the above explanation, we can see that struggling to perform is not an early sign of heat illnesses.

When I bumped the table, the coffee in my cup spilled out. Newton's _____ law explains this reaction.

Answers

So we want to know which Newtons law explains the reaction when we bump into the coffee cup the coffee is spilled out. So Newtons 1st law says that a body stays in motion or it stands still until a force acts on that body. So we acted by a force on the coffee cup and the coffee continued to move even if there was no force on the coffee after we bumped the coffee cup.
it would be his first law

A physical science test book has a mass of 2.2 kg what is the weight on mars??? please help

Answers

Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Test Book's weight on mars = 8.1 N.

What is different between mass and weight?

  • The distinction between Mass and Weight is Weight is a measure of force, while mass is a measure of inertia. Many people use these two terms interchangeably.
  • The mass of a body is the amount of matter contained within it, whereas the weight of a body is the force acting on it as a result of gravity's acceleration. In chemistry, this is the primary distinction between mass and weight.
  • Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Weight = (mass) x (gravity)

            = (2.2 kg) x (3.7 m/s^2)

              = 8.1 newtons
