What can you infer by looking at the electromagnetic spectrum (see image)? please get it right :(

Answer:

Radiation

Explanation:

The form of heat that does not require matter or particles to happen is known as radiation.

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia

Answer:

The gravitational force between two objects = F = 9.3 x 10⁻⁶ N        

Explanation:

Given

m₁ = 70 kg

m₂ = 2000 kg

distance r = 1 m

Thus, the gravitational force between two objects = F = Gm₁m₂ / r²

as

Gravitation constant = G = 6.67430×10⁻¹¹ N⋅m²/kg²  

Thus, putting the values

F = Gm₁m₂ / r²

  = (6.67430×10⁻¹¹ × 70 × 2000) / 1²

   = 9.3 x 10⁻⁶ N

Thus, the gravitational force between two objects = F = 9.3 x 10⁻⁶ N

Answer:

338.7cm

Explanation:

The can of corn would be in the shape of a cylinder. Since we are looking at capacity, we will want to find the volume.

V=abase×h

V=πr2×h

V=π(d2)2×h

V=π(6.62)2×9.9

V=338.7cm3

Hopefully this helps!

Answer:

338.7 cm³

Explanation:

For this question you use the volume formula of a cylinder πr²h.

Radius is 1/2 the diameter.

Simply input the variables into the formula.

π(3.3)²×9.9 = 107.811π or approximately 338.7 cm³

Inertia. Sometimes this first law of motion is referred to as the law of inertia. Inertia is the property of a body to remain at rest or to remain in motion with constant velocity.

Cosmic Dust.

Why? When stars explode, or die, they releases dust and gas.

To solve this we must be knowing each and every concept related to galaxy. Therefore, cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Galaxies are collections of stars as well as other celestial objects that are gravitationally bound. The cosmos contains and over 100 billion galaxies, each of which has stunning formations seen in photographs captured by telescopes of the far sky.

According to Samuel, a galaxy's shape is the result of continual interactions between its many components. The majority of the mass is provided by the dark matter, which uses gravity to hold everything together. Cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Therefore, cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Answer:

The range is 15.15 m and the time in the air is 1.01 s

Explanation:

Horizontal Motion

When an object is thrown horizontally (with angle 0°) with a speed v from a height h, it follows a curved path ruled exclusively by gravity until it eventually hits the ground.

The range or maximum horizontal distance traveled by the object can be calculated as follows:

[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]

To calculate the time the object takes to hit the ground, we use the equation below:

[tex]\displaystyle t=\sqrt{\frac{2h}{g}}[/tex]

The cannon is shot from a height of h=5 m with an initial speed of v=15 m/s. The range is calculated below:

[tex]\displaystyle d=15\cdot\sqrt{\frac {2*5}{9.8}}=15*1.01[/tex]

d = 15.15 m

The time in the air is:

[tex]\displaystyle t=\sqrt{\frac{2*5}{9.8}}[/tex]

t = 1.01 s

The range is 15.15 m and the time in the air is 1.01 s

Answer:

Explanation:

Answer:

Imp = 20000 [kg*m/s]

Explanation:

In order to solve this problem we must divide it into two parts. In the first part we must use the following equation of kinematics.

[tex]V_{f}=v_{i}-a*t[/tex]

where:

Vf = final velocity = 0 (the car stops)

Vi = initial velocity = 20 [m/s]

a = acceleration [m/s²]

t = time = 0.5 [s]

Acceleration is negative as the cart slows down as it stops.

[tex]0=20-a*0.5\\20=0.5*a\\a=40 [m/s^{2}][/tex]

The second part is the determination of momentum, which is defined as the product of force over a given time. But to determine the force we must use Newton's second law which tells us that the sum of the forces of a body is equal to the product of mass by acceleration.

∑F = m*a

[tex]F = 1000*40\\F = 40000[N][/tex]

Now the impulse or momentum

[tex]Imp = F*t\\Imp = 40000*0.5\\Imp=20000[kg*m/s][/tex]

Answer:

I think that is d option 1.0Nm anticlockwise

Answer:

acceleration due to gravity is constant anywhere on the earth .its value is 9.8m/s²

Explanation:

If acceleration points in the same direction as the velocity, the object will be speeding up. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.

Answer:

The value of the horizontal velocity when the pumpkin is thrown is approximately 17.619 m/s

Explanation:

The height from which the pumpkin is thrown = 14 meters

The velocity with which the pumpkin is thrown = 23 m/s

The direction in which the pumpkin is thrown = 40° above the horizontal

The horizontal component of the velocity = 23 × cos(40) ≈ 17.619

Therefore, the value of the horizontal velocity when the pumpkin is thrown ≈ 17.619 m/s

Explanation:

Hi! It would be A. Plane mirrors produce only virtual images,and concave mirrors produce real and virtual images.

Plane mirrors construct only virtual images, and concave mirrors make real and virtual images. Thus, this statement best corresponds concave and plane mirrors.

A virtual image exists represented as the opposite of a real image, thus an image that cannot be obtained on a screen stands produced as a virtual image. The motivation for this exists in the fact that the beams of light that form a virtual image never connect therefore a virtual picture can never be projected onto a screen. Examples: Image formed in a plane mirror, an image constructed on the front and back surfaces of a spoon, etc.

Therefore, the (A) option exists as the accurate answer.

Answer:

Mercury shows faster increase in temperature than water on heating because the mercury has less specific heat capacity than water.

The specific heat capacity is defined as the amount of heat to required by a mass of a material to make a unit change in its temperature.  Mercury has less specific heat capacity and shows immediate changes in the temperature. Because of this mercury is used in thermometers and not water.
