Answer:

B. B

Explanation:

As we know that convective zone is that part of the sun where heat is primarily transferred by convection mode. In this part of sun major proportion is gas so that heat is transferred by gas molecules.

So here we will have

outer most part of the sun is E = CORONA

then it is the surface of sun which is A = PHOTO SPHERE

Then the inner part to the surface of sun is B = CONVECTIVE ZONE

then the next inner part is vacuum where heat is transfer by C = RADIATE ZONE

Then the innermost part of the sun is its D = CORE

so correct answer will be B

When the electrons reach the collector, they flow towards the positivly charged grid. The resulting current is measured. Note th

Masja [62]

Answer:

We can conclude by saying that in the beginning current will increase but after sometime, it becomes saturated.

Explanation:

Note: No information on change in number of electron generated.

Since there is a collision, the electrons emitted will not reach the collector at same time. As the voltage is increased, the the speed with which the electrons will reach the collector starts to increase. Due to this, electric current will first increases till all the emitted electrons reach the collector. Since we are not provided with the information that number of electrons generated are changing, after increasing voltage current will increase for some time and then reaches a saturated state.

We can conclude by saying that in the beginning current will increase but after sometime it becomes saturated.

in 1984 don, disk that stayed aloft for 16.7 seonds supsuppose cain ran up a staricase during this time, reachig a height of 18.

laila [671]

Answer

given,

time of disk stayed a loft = 16.7 sec

height reached = 18.4 m

mass = 72 kg

now work done is equal to change in potential energy

$W = - (U_f - U_i)$

$W = - (mgh - 0)$

$W = - (72\times (-9.8) \times 18.4)$

W = 12983.04 J

Positive sign means that work is in the direction of motion.

$Power = \dfrac{Work\ done}{time}$

$Power = \dfrac{W}{t}$

$Power = \dfrac{12983.04}{16.7}$

P = 777.42 Watts

If you take two steps of different sizes, can you end up at your starting point (in other words, can two vectors with different

vfiekz [6]

Answer:

a) No, Two vectors with different magnitudes can never add up to zero.

b) Yes, Three or more vectors with different magnitudes can add up to zero.

Explanation:

a) No, Two vectors with different magnitudes can never add up to zero.

Given vector A and B

A = (x1,y1,z1) and B = (x2,y2,z2)

For A + B = 0

This conditions must be satisfied.

x1 + x2 = 0

y1 + y2 = 0

z1 + z2 = 0

Therefore, for those conditions to be meet the magnitude of A must be equal to that of B.

b) Yes, Three or more vectors with different magnitudes can add up to zero.

For example, three forces acting at equilibrium like supporting the weight of a person with two different ropes.

W = T1 + T2

Where;

W = Weight

T1 = tension of wire 1

T2 = tension of wire 2
