2. Adelia holds a shiny steel spoon with its back (convex surface) facing her eyes at a distance

Physics
1 answer:
My name is Ann [436]3 years ago
3 0

Answer:

(a) The convex mirror image, is always upright at all positions, while images formed by concave mirrors are always inverted when the object distance from the mirror is more than the mirrors focal length.

(b) An upright image is not seen for object at a distance from a concave mirror further than the focal length of the mirror, which is the spoon in the question

Therefore, the location of her eyes of approximately, 30 cm,  from the mirror is more than the mirror's focal length

A diamond with a mass of 45 g hangs motionless from a chain. what is the upward force of the chain on the diamond?
BARSIC [14]
The upward force of the chain on the diamond would be the tension in the chain, and this tension would have to support the weight of the 45g that hangs from the chain.

mass = 45 g = 45/1000 kg = 0.045kg

Weight = mg = 0.045 * 10 ≈ 0.45N,            g ≈ 10 m/s²

So the upward force is ≈ 0.45N.

The gravitational force exerted by a proton on an electron is 2x1039 times weaker than the electric force that the proton exerts
pickupchik [31]

To solve this problem we will rely on the theorems announced by Newton and Coulomb about the Gravitational Force and the Electrostatic Force respectively.

In the case of the Force of gravity we have to,

F_g = G\frac{m_pm_e}{d^2}

Here,

G = Gravitational Universal Constant

m_p = Mass of Proton

m_e = Mass of Electron

d  = Distance between them.

F_g = (6.673*10^{-11} kg^{-1} \cdot m^3 \cdot s^{-2}) (\frac{(1.672*10^{-27}kg)(9.109*10^{-31})}{(52.9pm)^2})

F_g = 3.631*10^{-47}N

In the case of the Electric Force we have,

F_e = k\frac{q_pq_e}{d^2}

k = Coulomb's constant

q_p = Charge of proton

q_e = Charge of electron

d = Distance between them

F_e = (9*10^9N\cdot m^2 \cdot C^{-2})(\frac{(1.602*10^{-19}C)(1.602*10^{-19}C)}{(52.9pm)^2})

F_e = 82.446*10^{-9}N

Therefore

\frac{F_e}{F_g} = 2.270*10^{39}

We can here prove that the statement is True

A boat is moving towards east with a velocity 4m/s with respect to still water and the river is flowing towards north with veloc
poizon [28]
Refer to the figure below.

The velocity diagram adds the speed of the boat (due east) as a vector to the combined speed of the water and the wind (due north) to obtain the velocity of the flag, at an angle θ,  counterclockwise from the eastern direction.

By definition,
tan θ = 8/4 = 2
θ = arctan(2) = 63.4°

Answer:
The flag blows in a direction which is 63.4° measured counterclockwise from the eastern direction.

Since a kilogram of feathers and a kilogram of lead have the same mass, how do they appear different and why?
Alchen [17]
They do have the same mass. However, “Heavy” implies we are concerned with how much force it takes to lift the object. In this case, we will find that the force needed to lift a kilo of feathers in air is slightly less than that needed to lift the kilo of lead.
