in a system of gas, if we double the temperature what happens to the energy of the particles?

if we neglect air friction, then we can conclude that the acceleration vector of the football is  not accelerating horizontally.

The acceleration vector of the football, neglecting air friction, is directed downward with a constant magnitude of 9.8 m/s^2, which is equal to the acceleration due to gravity. This is because the only force acting on the football is gravity, which pulls it toward the center of the earth, and the direction of the acceleration is equal to the direction of the gravitational force. So, the acceleration vector of the football is given by:

a = (0, -9.8 m/s^2)

where the x-component is 0, because the football is not accelerating horizontally, and the y-component is -9.8 m/s^2 because the acceleration is directed downward.

Answer:

The order of magnitude of the number of wavelengths of red light in 1.0m is B) 10^6.

Explanation:

The wavelength of red laser light is around 700 nm, or 7 x 10^-7 meters. Therefore, the number of wavelengths of red light in 1.0 meter is (1.0 m) / (7 x 10^-7 m) = 1.0 / 7 x 10^-7 = 1.0 / 7 x 10^7 = approximately 10^7. The order of magnitude is 10^6.

Eyes of circular aperture of diameter 4.8 mm. The light of wavelength 536 nm used to view the two point sources that are 140 m. The far apart must be the two point of source, if they are to just resolved by the eyes is  1.8 × 10⁻⁵ cm  cm.

The wavelength =  536 nm

The diameter = 4.8 mm

The heat of the sun had to be used to generate steam  was necessary to generate usable electricity for a home.

Electronics known as solar cells are used in solar photovoltaic (PV) systems to convert sunlight directly into electricity. The PV cells on a solar panel capture the energy from the sun's rays as it shines on the panel. In reaction to an internal electrical field within the cell, this energy generates electrical charges that move, which results in the flow of electricity. Chemical reactions between solar photons and silicon crystals produce an electron flow. Nevertheless, because to the high cost and difficulty in obtaining silicon crystals of adequate quality, household solar systems are often built using equivalent but less expensive parts like copper, indium, gallium, and selenide (CIGS).

Gravitational field strength on the surface of Mars is approximately 3.71 m/s².

Gravitational field is a model used to explain the influences that massive body extends into the space around itself, producing force on another massive body.

The gravitational field strength (g) on the surface of a planet can be calculated using the formula:

g = GM / r²

where G is the gravitational constant (6.67 x 10⁻¹¹ Nm²/kg²), M is the mass of the planet, and r is the radius of the planet.

Plugging in the values for Mars:

g = (6.67 x 10⁻¹¹ Nm²/kg²) x (6.37 x 10²³ kg) / (3.43 x 10⁶ m)^2

g = 3.71 m/s²

a. We first solve the differential equation to obtain the expression for I before determining the depth, x.  

dI/dx = (-1.21)I

dI = (-1.21)Idx

dI/I = -1.21dx

Integrating both sides, we have

∫dI/I = ∫-1.21dx

㏑I = -1.21x + C

I = exp(-1.21x + C)

I = exp(-1.21x)exp(C) Let exp(C) = A

I =Aexp(-1.21x)

when x = 0, I = L. When these are substituted into the equation, we have

L = Aexp(-1.21 × 0)

L = Aexp(0)

L = A

So, I = Lexp(-1.21x)

When I = L/2, we want to determine x.

So, L/2 = Lexp(-1.21x)

1/2 = exp(-1.21x)

-1.21x= ㏑(1/2)

-1.21x= -㏑2

x = -㏑2/-1.21

As a result, the bird's instantaneous speed at t=8.00s is 2.1 m/s.

A particle or object's motion with regard to time is expressed vectorially as its velocity. The recognized unit of velocity magnitude is the metre per second (m/s), which is frequently used to refer to as speed. A different way to express velocity magnitude is in centimeters per second (cm/s). When observed from a certain point of reference and measured according to a specified standard of time (for instance, 60 km/h northbound), velocity is the rate of change in direction of an item in motion.

The velocity of an object is the distance it travels in a predetermined period of time. This word equation illustrates the relationship between space, time, and speed: The velocity is calculated by dividing the total distance traveled by the total journey time. In physics, velocity is a vectorial measure of a motion's speed and direction.

The rock and the projectile pass each other at a height of 25.1 m,  the projectile does make it to the top of the building and the rock takes 3.12 seconds before falling to the ground.

Given the height of building (h) = 35m

The initial speed of rock (u) = 5m/s

The speed of cannon on the ground (u1) = 30m/s

We know that from Newtons laws of motion h = ut + 1/2at^2 where t is the time taken and a is the acceleration, h is the height reached.

For the rock 35 = 5 x t + 1/2(-g)t^2 since going downwards a = -g

For the cannon 0 = 30 x t + 1/2(-g)t^2

Since they both meet at the same point then:

35 - 5 x t + 1/2(-g)t^2 = 30 x t + 1/2(-g)t^2

35 = 35 x t

t = 1s

So, it will take 1s for them to reach the same height.

Then the height they meet = 35 - 5 x 1 - 1/2 x 9.8 x 1^2 = 25.1m

(b) The maximum height reached by canon = v^2 - u^2 = 2as

The projectile reaches the top of the building.

The heavier block of mass 6kg here is being pushed by a horizontal force of 20 N. As both the blocks are in contact with each other, this means that both move with the same acceleration. Acceleration in terms of the above relation:
