When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the s

ky diver and, thus, slows him down. Suppose the weight of the sky diver is 968 N and the drag force has a magnitude of 1085 N. The mass of the sky diver is 98.8 kg. Take upward to be the positive direction. What is his acceleration, including sign

Answer:

The value a = 1.1842 \ m/s^2

Explanation:

From the question we are told that

The weight of the sky diver is W =  968 \  N

The magnitude of the drag force is D_f  =  1085 \  N

The mass of the sky diver is m  =  98.8 \ kg

Generally the net force acting on the sky diver is mathematically represented as

F = m * a  =  D_f  - W

Hence the acceleration of the sky diver is mathematically represented as

a =  \frac{D_f - W}{ m}

=> a =  \frac{1085 - 968}{  98.8}

=> a = 1.1842 \ m/s^2

The grounded conductor and the grounding conductor are one and the same conductor and perform the same function.
STALIN [3.7K]

Answer:

Grounded  used to carry the current in the normal conditions. while on the other side grounding is refer to that safety wire that is connected to the earth and currently does not transmit through it.

As grounding wire is referred to as safety wire hence it carries current only in an emergency like a short circuit.

Explanation:

A grounded conductor is referred to as one of the wire that needed in an electric circuit. it is basically a neutral conductor.  It used to carry the current in the normal conditions. while on the other side grounding is refer to that safety wire that is connected to the earth and currently does not transmit through it.

As grounding wire is referred to as safety wire hence it carries current only in an emergency like a short circuit.

A=(v – u)/t<br><br> i. V as subject<br> ii. U as subject<br> iii. T as subject
Norma-Jean [14]

Answer:

i.

a =  \frac{(v - u)}{t}  \\ v - u = at \\ v = at + u

ii.

a =  \frac{(v - u)}{t}  \\ v - u = at \\ u = v - at

iii.

a =  \frac{(v - u)}{t}  \\ ta = v - u \\ t  =   \frac{(v - u)}{a}

I hope I helped you^_^

How can you give a baloon an electric charge
vodka [1.7K]

When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons.

A grating has 460 rulings/mm. What is the longest wavelength for which there is a 6.0th-order diffraction line
mestny [16]

Answer:

λ = 3.62 x 10⁻⁷ m = 362 nm

Explanation:

The grating equation gives the relationship between the wavelength, the diffraction line order and the diffraction angle. The grating equation is written as follows:

mλ = d Sinθ

where,

m = order of diffraction = 6

λ = longest wavelength = ?

d = 1/(460 rulings/mm)(1000 mm /1 m) = 2.17 x 10⁻⁶ m/ruling

θ = Diffraction angle = 90° (for longest wavelength)

(6)λ = (2.17 x 10⁻⁶ m/ruling) Sin 90°

λ = (2.17 x 10⁻⁶ m/rulings)/6

<u>λ = 3.62 x 10⁻⁷ m = 362 nm</u>
