An engineer is designing the foundation of large building and wants to be sure that movement in the ground will do as little damage to the building as possible. Which building material would be best to use in the foundation?

Answer:

Height and Velocity Functions

Explanation:

Multiply the height by 2, and divide the result by the object's acceleration due to gravity. If the object fell from 5 m, the equation would look like this: (2*5 m)/(9.8 m/s^2) =1.02 s^2.

Answer:

Acceleration = Final velocity - initial velocity / time take

65-35=30 , 30/5=6

Acceleration = 6m s-2

Explanation:

Answer:

The reason it hurts more to fall on a concrete floor than on grass is due to a combination of factors

When you fall, your body's momentum causes it to continue moving until it comes into contact with an object that can stop it. When you fall on a concrete floor, the surface is hard and rigid, which means that it can stop your body's motion more quickly and with more force. This results in a greater impact force on your body, which can cause more damage and more pain.

On the other hand, when you fall on grass, the surface is soft and yielding, which means that it can absorb some of the impact force. This results in a lower impact force on your body and therefore less damage and less pain.

Another factor that comes into play is the time of contact. When you fall on a concrete floor, the time of contact is shorter, which means that the impact force is concentrated over a shorter period of time. This can increase the intensity of the force and make it more painful. On the other hand, when you fall on grass, the time of contact is longer, which means that the impact force is spread out over a longer period of time. This can decrease the intensity of the force and make it less painful.

In summary, it hurts more when you fall on a concrete floor than on grass because the concrete floor is a harder surface that can stop your body's motion more quickly and with more force, resulting in a greater impact force and a shorter time of contact.

Answer:

15 units NE

Explanation:

Assuming the coordinate plane is a compass with N being the positive y-axis, we can use the Pythagorean theorem to find the magnitude of the vector. Since the vector is going up by 12 and right by 9 at the same time, it should form a diagonal line, aka the hypotenuse of a triangle. This triangle has both of its leg units as 12, and 9. Pythagorean theorem states that a^2 + b^2 = c^2, that is both of their legs squared is the hypotenuse of the triangle squared. 12^2 + 9^2 = c^2. c = 15. Now that we know the magnitude, let's go back to the quadrants as the compass. Since both units are positive, the vector goes in the positive direction on both sides, which is Quadrant 1. North and East would be the appropriate say for the vector's direction, thus the vector's direction will be 15 units North East.

The top ones being parallel gives 1/(1/30 + 1/40) = 120/7 ohms. The rightmost path in series gives 30 ohms, and then the parallel pair on the right is 1/(1/50 + 1/30) = 75/4 ohms. I = V/R => 9 / (75/4+120/7) \(\approx\) .25A

Radiative energy is the energy carried by light.

What is radiative energy?

Radiative energy is the energy carried by light. It is a form of energy that can be transmitted through space without requiring a medium for it to move through. Radiative energy can come from natural sources like the sun or artificial sources like light bulbs.

Radiative energy is important for a variety of reasons. For one thing, it is the primary source of energy for many living organisms on Earth, particularly plants. Energy from the sun helps plants photosynthesize and produce food that they can use to grow and reproduce.

Radiative energy is also important for human life. It is used in a variety of ways, including in the form of light for illuminating spaces and in the form of heat for cooking and keeping warm. Understanding the nature and properties of radiative energy is important for a wide range of scientific and technological fields.

Answer:

A. 119kg

B.0.53m from head

Explanation:

A. Weight = 730+340.

=1170N

F= Wg

W = 1170/9.8

= 119kg

If x is distance from head to CG then 1.92–x is the other distance.

Moments must equal

470x = 330(1.89–x)

470x = 623.7 – 330x

1170x = 623.7

x = 0.53m from head

The closer a planet is to the sun, the shorter its period of revolution. The farther away a planet is from the sun, the longer its period of revolution.

Explanation:

i hope that helps, have a great day.

Answer:

The closer a planet is to the sun, the shorter its period of revolution. The farther away a planet is from the sun, the longer its period of revolution. so it depends on how close and how far it is to have a different time period. so if the if it is close then the period of revolution will be shorter because they need more space to have a longer period. if it is spaced out then it will have a longer period because they do have space.

The lowest frequency infrared waves are those listed below. The wavelength range of infrared (IR) is between 780 nm to 1 mm, while its frequency range is between 300 GHz and 400 THz.

The correct answer is D

An element of the electromagnetic spectrum is infrared waves or infrared light. The human eye cannot perceive infrared waves, but people can feel their heat. Infrared waves are everywhere around us. To change the channel on your TV, a remote control sends out infrared light waves, which are just beyond the visible light range.

Irradiation (IR) is electromagnetic radiation, a type of wave-moving energy. The heat it emits is identical to what we experience from the Sun and is entirely natural. Far-infrared waves are being projected into the area by our radiators, and as they hit people and objects in the environment, they will be reflected back and heat them up.

Answer:

The best explanation is that the first person is grounded to the earth, and his/her body either draws up negative charges from the earth, or tend to conducts negative charges to the earth, depending on the charge on the balloon.

Explanation:

The earth is an infinite store for charges. In the first case where the second person brings a negatively charged balloon towards the first person, the negative charges on the balloon induces the first person's body to tend to attract the negative charges on the balloon through the first person's body to the positive charges within the earth. In the second case when again a positively charged balloon is brought near the first person's hair, the positive charges on the balloon induce the first person's body into drawing up negative charges from within the earth. This charges, and their opposite induced charges, create an attractive force between the hair strands and the balloons.

c) 90°  = π/2 radian.

d) 360°  = 2π radian.

e) 420°= 7π/3 radian.

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.

Relationship between degree and radian is:

1° = π/180 radian.

So, a) 30° = 30π/180 radian = π/6 radian.

b) 57° = 57π/180 radian = 0.32π radian.

c) 90° = 90π/180 radian = π/2 radian.

d) 360° = 360π/180 radian = 2π radian.

e) 420° = 420π/180 radian = 7π/3 radian.

Explanation:

Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.

Insulators are those substances that do not conduct heat or electricity like their conductor counterparts.

Conduction of electric charges is as a result of the free flow of electrons in the atom of the substance.

Hence, a good insulator holds on tightly to its electrons and prevent them from flowing freely to conduct electric charges.

Therefore, Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.

mass = 444.44 kg

Explanation:

To calculate the mass of the truck, we can use the formula for momentum:

Momentum (p) = mass (m) × velocity (v)

Given:

Momentum (p) = 40,000 kg·m/s

Velocity (v) = 90 m/s

We can rearrange the formula to solve for mass (m):

m = p / v

Substituting the given values:

m = 40,000 kg·m/s / 90 m/s

m ≈ 444.44 kg

Therefore, the mass of the truck is approximately 444.44 kg.
