Answer:

Explanation:

This is a displacement vector since it is given in terms of a distance (meters, to be specific). The way you find the x-component is:

[tex]V_x=Vcos\theta[/tex] which means you multiply the magnitude (length) of the vector times the cos of the direction (the angle):

[tex]V_x=2.5cos(64)[/tex] to get

Input force of pulley system = 200 N

Explanation:

Given:

Mechanical advantage of pulley system = 5

Output force from pulley system = 1,000 N

Find;

Input force of pulley system

Computation:

Mechanical advantage = Output force / Input force

Mechanical advantage of pulley system = Output force from pulley system / Input force of pulley system

5 = 1,000 / Input force of pulley system

Input force of pulley system = 1,000 / 5

Input force of pulley system = 200 N

Answer:

R = 1.71 ohms

Explanation:

Two resistors are connected in parallel. There equivalent resistance is given by :

Put all the values,

[tex]\dfrac{1}{R}=\dfrac{1}{3}+\dfrac{1}{4}\\\\R=1.71\ \Omega[/tex]

So, the resultant resistance of the circuit is equal to 1.71 ohms.

Explanation:

During the day the sky looks blue because it's the blue light that gets scattered the most. It's redirected into many different directions all over the sky, whereas the other wavelengths aren't scattered as much. Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. White light is composed of seven light and among them, blue light scatters the most as the wavelength of the blue light is comparable to the size of particles in the atmosphere. So, the sky appears blue. Hence, the sky appears blue because the fine particles in the atmosphere scatter light of shorter wavelengths! :D

Answer:

The formula is correct.

Explanation:

The given expression is :

[tex]v^2=2gh[/tex]

Where

v is the velocity

g is acceletion due to gravity

h is height

Taking LHS,

The dimensional formula for [v] = [LT⁻¹]

[v²] = [L²T⁻²]

Taking RHS,

The dimensional formula for [g] = [LT⁻²]

The dimensional formula for [h] =[L]

2gh = [LT⁻²][L]

= [L²T⁻²]

So, LHS =  RHS

So, the given formula is correct dimensionally.

Answer:

Answer:

In the first one circle : luster

second circle: atsuete seeds

third: dentures

Explanation:

Well I ain’t sure

Answer:

Solon,

total mass (kg)= 100kg

height (h)= 25m

acceleration due to gravity = 9.8m/s²

so,

work done =m*g*h

= 100*9.8*25

= 24,500 joule

The work done by the crane in lifting the given mass of concrete to the given vertical height is 24500 Joules.

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

W = F × d

Where f is force applied and d is distance travelled.

Note that, the concrete is lifted upward, Weight of the concrete becomes mass multiply by acceleration due to gravity. g = 9.8m/s²

F = Weight = mg

Given that;

W = F × d

W = (mg) × d

W = ( 100kg × 9.8m/s² ) 25m

W = 980kgm/s² × 25m

W = 24500kgm²/s²

W = 24500J

Therefore, the work done by the crane in lifting the given mass of concrete to the given vertical height is 24500 Joules.

Answer: 24.39 N

Explanation:

Given

Torque required to open the lid is [tex]\tau =2\ N.m[/tex]

diameter of lid [tex]d=8.2\ cm[/tex]

Force exerted by fingers and thumb forms a couple. So, torque can be written as

[tex]\Rightarrow \tau= F\times 2r\\\Rightarrow 2=F\times 8.2\times 10^{-2}\\\\\Rightarrow F=\dfrac{200}{8.2}\\\\\Rightarrow F=24.39\ N[/tex]

Thus, the magnitue of each force is 24.39 N

Answer:

Its gravitational potential energy must increase.

Explanation:

Conservation of Mechanical Energy

The total amount of mechanical energy, in a closed system in the absence of dissipative forces like friction or air resistance, remains constant.

This means that energy cannot disappear or appear and that potential energy can become kinetic energy or vice versa.

In a closed system like a pendulum, two types of energies are considered: Gravitational potential (U) and kinetic (K). Thus, the sum of both energies must remain constant in time.

Suppose the pendulum is at a state where U=150 J, and K=350 J. The total mechanical energy is:

M = 150 J + 350 J = 500 J

If the kinetic energy decreases to a new value, say K = 200 J, then the gravitational potential must increase to compensate for this new condition, that is: U = 300 J

So, It's gravitational potencial energy must increase

Answer:

Concave mirrors reflect light to a central point (converging)

Suppose the source is to the left of the  mirror in  question.

Parallel rays into the mirror are always reflected towards the focal point.

In the case of a concave mirror the real parallel rays pass thru the focal point.

If the mirror is convex the rays will diverge to the left and act as if they were emanating from the focal point to the right of the mirror.
