Why is it incorrect to say that astronauts are weightlesS in space while orbiting Earth in a space shuttle?​

So, the power rating of that LED light bulb is 9 Watt.

Hi ! I will answer your question. This material is about electricity where You are instructed to calculate the rated power of a lamp. Always remember, the power required by the lamp must also be at least the same as the power from the mains so that the light is not too dim or the lamp does not explode.

In this question, the formula used is the formula for calculating power, which is the product of the voltage and current flowing. It can be seen mathematically as below:

[tex] \boxed{\sf{\bold{P = V \times I}}} [/tex] Or

[tex] \boxed{\sf{\bold{P = \frac{V^2}{R}}}} [/tex]

With the following condition :

We know that :

What was asked :

Step by step :

[tex] \sf{P = V \times I} [/tex]

[tex] \sf{P = 18 \times 0.5} [/tex]

[tex] \boxed{\sf{P = 9 \: Watt}} [/tex]

So, the power rating of that LED light bulb is 9 Watt.

Answer: The resultant displacement vector is 5.6km

The resultant displacement vector of the hiker is equal to 5.6 km.

The distance can be described as the total length traveled by an object and is a scalar quantity with only magnitude. The distance should be always positive.

The displacement of an object can be described as the shortest length between two points. The displacement can be considered as a vector quantity with direction & magnitude. The displacement can be +ve, -ve, or zero and can be changed with time.

Given, a hiker moves 5.0 km along AB in the North and then 2.5 km west along BC.

The length (AC) is the resultant displacement that can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (5.0)² + (2.5)²

AC² = 25 + 6.25

AC = 5.59 km ≈ 5.6 km

Therefore, the displacement of the hiker is 5.6 Km.

The radius of each jawbreaker is approximately 0.68 cm.

where

r = radius

Therefore,

23 g  = 32.3 cm³

0.94 g  = ?

cross multiply

volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³

Therefore,

volume of each jawbreaker = 4 /3 πr³

1.32 = 4 / 3 × 3.14 × r³

r³ = 1.32 /4.18666666667

r³ = 0.31533683707

r = ∛0.31533683707

r = 0.680651651 = 0.68

Therefore, the radius of each jawbreaker is approximately 0.68 cm.

Explanation:

The sulphur atom has 6 electrons in the outermost shell, and its valency could be 6. But it is easier for sulphur to gain two electrons instead of losing six electrons. Hence, its valency is determined by subtracting six electrons from the octet and this gives a valency of two for sulphur.

Answer:

5 m/s2

Explanation:

Using the equation velocity = initial velocity + (acceleration x time)

30 m/s = 0 + acceleration x 6 s

30 m/s = 6 s x acceleration

30 m/s / 6s = acceleration

acceleration = 5 m/s2

Answer: 4500 m

Friction is the force that opposes motion.

The term friction refers to the force that hinders the movement of a surface over another. The frictional force depends on the nature of the surfaces in contact.

1) The two forces acting on the ball during the frictional force are the forward force and the frictional force.

2) The ball takes more time to roll down the incline in the presence of the cloth because of the increase in friction of the surface.

A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.

Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.

A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.

v² = u² + 2 × a × s

v² = (0 m/s)² + 2 × (9 m/s²) × 240 m

v = 66 m/s
