Physics
1 answer:
BARSIC [14]4 years ago
5 0

Answer:

Many people are familiar with kilogram calories, which are often used to measure the energy available in food.

Explanation:

Quantities of energy given in one unit can always be converted to any other unit of energy. For example, 1 gram calorie is equivalent to 4.186 joules, which is used to measure heat energy.

trasher [3.6K]

Answer: B. A gravitational field

Explanation:

Surrounding earth is gravitational field. Gravitational field is a region of space were gravitational force can be felt and gravitational force is the gravitational pull on the surface of the earth. The presence of this gravity is what allow us to be able to walk freely without falling. It also make us jump up and be able to land back on the ground. Assuming there are no force of gravity in the surface of the earth, there won't be any possibility of landing back on the ground after jumping.

A particle passes through the point P=(−3,1,0)P=(−3,1,0) at time t=3t=3, moving with constant velocity v⃗ =⟨5,3,−2⟩v→=⟨5,3,−2⟩.
eimsori [14]

Answer:

The parametric equation for the position of the particle is (-18+5t,-8+3t,6-2t).

Explanation:

Given that,

The point is

P=(-3,1,0)

Time t = 3

Velocity v=(5,3,-2)

We need to calculate the parametric equation for the position of the particle

Using parametric equation for position

r(t)=r_{0}+v(t)t....(I)

at t = 3,

P=r(t)

Put the value into the formula

(-3,1,0)=r_{0}+(5,3,-2)\times3

(-3,1,0)=r_{0}+(15,9,-6)

r_{0}=(-18,-8,6)

Put the value of r₀ in equation (I)

r(t)=(-18,-8,6)+(5,3,-2)t

r(t)=(-18+5t,-8+3t,6-2t)

Hence, The parametric equation for the position of the particle is (-18+5t,-8+3t,6-2t).

if an objects first movement is 3.0m North and another movement is 4.0m West, what is the magnitude of the displacement made ove
Snezhnost [94]

If an object's first movement is 3.0m North and another movement is 4.0m west, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.

<h3>What is displacement?</h3>

Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.

As given in the problem if an object's first movement is 3.0m North and another movement is 4.0m west

Resultant displacement can be calculated with the help of the triangle law of the vector addition,

Resultant = √( 3² + 4²)

                =√25

                = 5.0 m

Thus, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
