What is the thermal energy least to greatest
A cup of coffee
An ocean
An ice cube
A cooked turkey
A huge iceberg

Answer:

28 N

Explanation:

From the question given above, we were told that 10 N force and 18 N force act in the same direction on the object.

The net force acting on the object can be obtained by simply adding both forces together since they both act on the object in the same direction. This is illustrated below:

Force 1 (F₁) = 10 N

Force 2 (F₂) = 18 N

Net force (Fₙ) =?

Fₙ = F₁ + F₂ (since they both act in the same direction)

Fₙ = 10 + 18

Fₙ = 28 N

Therefore, the net force acting on the object is 28 N.

Hey I'm working on this test right now, did you ever get the answers?

Answer:

It is A, B, and C

Explanation:

I just took the test!

The three characteristics mechanical waves and electromagnetic waves share are:

A. The waves begin with a disturbance.

B. The waves transfer energy from its source.

C. The waves and their energy move outward from the source.

       Usually, waves transfer energy from one place to another. Mechanical waves transfers via matter where as electromagnetic waves transfers via light. Both mechanical waves and electromagnet (light) waves measured through amplitude, wavelength, frequency and both will get transmitted, refracted, reflected, absorbed, diffracted when they react with matter. Both the electromagnetic waves and mechanical waves are transverse in nature but the mechanical waves can also be in longitudinal.

So, many characteristics were similar for mechanical waves and electromagnetic waves.

Hence, Option A, B, C are the three characteristics.

Answer:

333 m

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s.

Time (t) = 8.14 s.

Final velocity (v) = 80.79 m/s.

Acceleration due to gravity (g) = 9.8 m/s²

Height (h) =?

v² = u² + 2gh

80.79² = 0 + (2 × 9.8 × h)

6527.0241 = 0 + 19.6h

6527.0241 = 19.6h

Divide both side by 19.6

h = 6527.0241 / 19.6

h = 333 m

Thus, the plane was at a height of 333 m when the package was dropped.

a) N = 343 [N]

Explanation:

We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.

[tex]N=m*g[/tex]

where:

m = mass = 35 [kg]

g = gravity acceleration = 9.81 [m/s²]

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

Answer:

The distance covered along the horizontal axis is [tex]s = 360 \ m[/tex]

The distance covered along the vertical  axis is  [tex]h = 78.4 \ m[/tex]

Explanation:

From the question we are told that  

    The horizontal velocity is  [tex]u_x = 90 \ m/s[/tex]

     The time considered is  [tex]t = 4 \ s[/tex]

Generally the distance which the bullet will cover in the horizontal direction for the given time is  mathematically represented as

    [tex]s = u_xt + \frac{1}{2}* at^2[/tex]

Here a is the acceleration along the horizontal direction and the value is  [tex]a = 0 \ m/s^2[/tex]

So

     [tex]s = 90 * 4 + \frac{1}{2}* * 0 * 4^2[/tex]

=>  [tex]s = 360 \ m[/tex]

Generally the distance which the bullet will cover in the vertical  direction for the given time is  mathematically represented as

            [tex]h= u_y t + \frac{1}{2}* gt^2[/tex]

Here  [tex]u_y[/tex] is the initial  velocity of the bullet along the vertical axis and the value is  [tex]u_y = 0 \ m/s[/tex]

             [tex]h = 0 * 4 + \frac{1}{2}* 9.8 *4^2[/tex]

=>          [tex]h = 78.4 \ m[/tex]

Answer:

To send a pulse of different speed, change the tension or stretch on the spring

Explanation:

A pulse is a single disturbance of a particle is a medium. The pulse has an amplitude or and a pulse length in the medium. The speed of the pulse is dependent on the amount of strain or tension ( stretch) applied to the medium. The speed also determines the length of the pulse but is unaffected by the or amplitude of the pulse.

Explanation:

Divide mass(m) by volume(v), you get density(D)

m/v=D

20/5=4

Answer:

d = - 10 [m]

Explanation:

We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.

[tex]v = d/t[/tex]

where:

v = velocity = 2 [m/s]

d = displacement [m]

t = time = 5 [s]

Now replacing:

Genetic engineering

Explanation:

Genetic engineering or also called genetic modification is the direct manipulation of an organism's genome in order to bring about a desirable trait in such organism. In genetic engineering procedure, the organism manipulated is called TRANSGENIC or GENETICALLY MODIFIED (GM) organisms.

In this case, a researcher is said to change the DNA (genetic material) in a soybean plant so that it produces offspring with a resistance to weed killer. This describes a genetic engineering procedure in which the soybean plant is manipulated to yield a desired trait, which is resistance to weed killer.

Answer:

b  Use a balance to determine the mass of the car. Use a motion sensor to measure the speed of the car at a time of 0s and at time of 5s .

Explanation:

The right way to measure the net force on the car is take the measurement of its mass then find the speed of the car within the time 0s to 5s.

This is because the net force acting on car is given as;

   Force  = mass x acceleration

By using the balance, the mass is determine

 Acceleration is the rate of change of velocity with time.

     Acceleration  = [tex]\frac{v - u}{t}[/tex]  

v is the final velocity

u is the initial velocity

t is the time taken

  Now,

         Force  = mass x  [tex]\frac{v - u}{t}[/tex]
