Answer:

Explanation:

Motion maps are those which represent the position, velocity and acceleration of any object taking different time intervals.

For maps of an accelerated motion, a new level indicates the change in acceleration or direction.

This change can be positive as well as negative. As a vehicle do not have uniform acceleration, it speed or direction may change at any interval of time which changes the acceleration and is represented on a graph.

Answer:

The correct answer is: change in acceleration or direction

Explanation:

Hello! Let's solve this!

The motion maps are graphs that show position, speed and acceleration. They show the direction of movement too.

Accelerated motion maps show acceleration and direction. Acceleration can be positive or negative depending on whether the acceleration is increasing or decelerating.

The correct answer is: change in acceleration or direction

What happens to the mantle and the plates at each type of plate boundary? How can you use the materials to show what happens? *
Lilit [14]

Answer:

Explanation:

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

You have 750 g of water at 10°C in a large insulated beaker. How much boiling water at 100°C must you add to this beaker so that
lina2011 [118]

Answer:

Correct answer:  m₂ = 1,950 g

Explanation:

When mixing the liquid, in this case water, at different temperatures, the warmer liquid will cool and the cooler will warm up until their temperatures equalize.

The amount of heat that the second fluid (water) releases is equal to the amount of heat that the first fluid (water) receives in this spontaneous process.

Q₁ = Q₂

Q₁ = m₁ c (t - t₁)    and Q₂ = m₂ c (t₂ - t)  

where are they:  m₁ = 750 g, t₁ = 10°C, t₂ = 100°C, t = 75°C, m₂ = ?

m₁ c (t - t₁)  = m₂ c (t₂ - t) \ : c

Since water is the liquid in question, it has the same specific heat capacity. Therefore, we will divide both sides of the equation by c and get:

m₁ (t - t₁)  = m₂ (t₂ - t) =>  m₂ = m₁ (t - t₁) / (t₂ - t) =>

m₂ = 750 · (75 - 10) / (100 - 75) => m₂ = 750 · 65 / 25 = 1,950 g

m₂ = 1,950 g

Seismic waves carry energy from earthquakes through the earth's crust. Seismic waves are...
Crank

Answer:

- longitudinal waves only

Explanation:

The P seismic waves travel as elastic motions at the highest speeds. They are longitudinal waves that can be transmitted by both solid and liquid materials in the Earth's interior.

Find the range of a projectile launched at an angle of 30° with an initial velocity of 20m/s.​
Tems11 [23]

Answer:

<em>The range is 35.35 m</em>

Explanation:

<u>Projectile Motion</u>

It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.

Being vo the initial speed of the object, θ the initial launch angle, and g=9.8m/s^2 the acceleration of gravity, then the maximum horizontal distance traveled by the object (also called Range) is:

\displaystyle d={\frac  {v_o^{2}\sin(2\theta )}{g}}

The projectile was launched at an angle of θ=30° with an initial speed vo=20 m/s. Calculating the range:

\displaystyle d={\frac  {20^{2}\sin(2\cdot 30^\circ )}{9.8}}

\displaystyle d={\frac  {400\sin(60^\circ )}{9.8}}

d=35.35\ m

The range is 35.35 m
