a scientist heats a piece of iron until it is glowing white–hot. he places the metal inside a metal box. he removes all of the a

ir from the inside of the box. after a few seconds, the sides of the box that are not touching the metal begin to feel warm. which process is most likely responsible for the warming? convection convection current radiation evaporation

Answer:

Radiation.

Explanation:

convection: The movement of heat through liquids.

convection current: The motion of moving the convection's mass.

radiation: The transfer of heat in wave like movements through electromagnetic waves.

evaporation: When a substance reaches its boiling point and turns to a gas.

So, since the heated iron is not touching any sides of the metal box, but the sides are still getting hot, the iron is radiating throughout the box.

Heat transfer through Radiation is responsible.

This is heat transfer that does not require a material medium or contact is not required.

A pilot heads his jet due east. The jet has a speed of 425 mi/h relative to the air. The wind is blowing due north with a speed
Alja [10]

Answer:

(a)Velocity of wind = 35 j

(b)Velocity of jet relative to air = 425 i

(c)True velocity of jet = 425 i + 35 j

(d)True speed of jet = \sqrt{425^{2}+35^{2}} = 426.88 mi/h

    Direction of jet is, ∅ = tan^{-1} \frac{40}{425} = 5.38°

Explanation:

We can represent east direction by i and north direction by j.

The jet has a relative speed of 425 mi/h relative to the air.

The wind is blowing due north with a speed of 35 mi/h = 35 j

425 mi/h is the relative speed with respect to wind that is

Velocity of jet wrt wind= V_{jw} = V_{j}-V_{w}

                               425 i = V_{j} - 35 j

V_{j} = 425 i + 35 j

(a)Velocity of wind = 35 j

(b)Velocity of jet relative to air = 425 i

(c)True velocity of jet = 425 i + 35 j

(d)True speed of jet = \sqrt{425^{2}+35^{2}} = 426.88 mi/h

    Direction of jet is,

     ∅ = tan^{-1} \frac{40}{425} = 5.38°

A robot on a basketball court needs to throw the ball in the hoop. The ball have a velocity of 10 m/s and an an angle of 60 degr
IRISSAK [1]

Answer:

Initial velocity = 10 m/s

θ = 60°

This is the case of projectile motion

So the horizontal component of velocity 10 m/s  =  10 cosθ

u = 10 cosθ

u = 10 cos 60°

u=5 m/s

x= 5 m

So in the horizontal direction

x = u .t

5 = 5 .t

t = 1 sec  The vertical component of velocity 10 m/s = 10 sinθ

Vo= 10 sinθ

Vo= 10 sin 60°

Vo = 8.66 m/s

V^2=V_o^2+2gh

0=V_o^2-2gh

0=8.66^2-2\times 10\times h

h=3.75 m

So height of robot = 3.75 - 0.75 m

   height of robot =3 m

Convert 2 kg to cg give you answer in SI
BARSIC [14]

1 kg=100000 cg

2 kg=200000 cq

If mass is the quantity then kg is the S.I

2 kg=2kg
