Answer:

Earth's core is important for three main reasons:

(1) it is responsible for the generation of Earth's magnetic field;

(2) it contains information regarding the earliest history of accretion of the planet; and

(3) thermal and compositional features established when the core formed have largely controlled the subsequent evolution of the core and also influence the evolution of the mantle, crust, and atmosphere

The function of a cell depends primarily on its ?
Schach [20]
<span>Organelles which are very important in giving nutrients. During cellular respiration, the food molecules such as glucose, are oxidized to carbon dioxide (CO2) and water (H2O) and trapped in ATP (Adenosine triphosphate) form for further us of cell’s activities. ATP’s are formed at mitochondria – the cell’s powerhouse. This type of organelle takes and breaks nutrients absorbed by the cell and creates energy afterward. The energy from ATP is then used by the body in kinetic activities like running & walking or involuntary activities like breathing, blood circulation, stimulus-responding, etc.</span>

An object with a mass of 2000 kg accelerates 8.3 m/s2 when an unknown force is applied to it. What is the amount of the force?
exis [7]

Answer:

<h2>16,600 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 2000 × 8.3

We have the final answer as

<h3>16,600 N</h3>

Consider two carts, of masses m and 2m, at rest on an air track. if you first push one cart for 3 s and then the other for the s
Marrrta [24]
F = m₁ a₁ = m₂ a₂

if m₁ = m and m₂ = 2m :

F = ma₁ = 2m  a₂ ⇒ a₁ = 2 a₂
 
since v = at + v₀  with t = 3, v₀ = 0 ⇒ v = 3a:

v₁ = 2 v₂

since p = vm with v₁ = 2v and v₂ = v :

p₁ = v₁m₁ = 2v ⁻ m
p₂ = v₂m₂ = v ⁻ 2m

p₁ = p₂

5. average A body sets off from rest with a constant acceleration of 8.0 m/s? What distance will it have covered after 3.0 s? 6.
chubhunter [2.5K]

Answer:

\boxed {\boxed {\sf 36 \ meters}}

Explanation:

We are asked to find the distance a body covers. We know the initial velocity, acceleration, and time, so we will use the following kinematic equation.

d= v_i t+ \frac {1}{2} \ at^2

The body starts at rest with an initial velocity of 0 meters per second. The acceleration is 8 meters per second squared. The time is 3.0 seconds.

  • v_i= 0 m/s
  • a= 8 m/s²
  • t= 3 s

Substitute the values into the formula.

d= (0 \ m/s)(3 \ s) + \frac{1}{2} (8 \ m/s^2)(3 \ s)^2

Multiply the first set of parentheses.

d= ( 0 \ m/s * 3 \ s) + \frac{1}{2} ( 8 \ m/s^2)(3 \ s)^2

d=0 \ m + \frac{1}{2} ( 8 \ m/s^2)(3 \ s)^2

Solve the exponent.

  • (3 s)²= 3 s* 3 s= 9 s²

d= 0 \ m + \frac{1}{2}( 8 \ m/s^2)(9 \ s^2)

Multiply again.

d= 0 \ m + \frac{1}{2} ( 72  \ m)

d= 36 \ m

The body will cover a distance of <u>36 meters</u>.

Do I have to choose physics to be an architect
horrorfan [7]
Physics is a very important part of Architecture. It helps you to understand how forces work on things that you build, so that they don't collapse. So yes, you do.
