Does heavy force work under conditions of weightlessness in such an artificial earth satellite?

1 answer:

3 0

Answer: That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.

Explanation: Because Earth-orbiting objects follow elliptical paths around Earth and not a straight line, forces cannot, by definition, be balanced. Force is directional. It is a push or a pull in a particular direction.

Suppose the demand for air travel decreases (as illustrated in the graph below). A decrease in demand _____ the equilibrium pric

vfiekz [6]

Answer:

decreases, decreases

Explanation:

A decrease in the demand will create a fall in equilibrium prices and the quantity supplied will also decrease. As the equilibrium prices in the market are the price in which the quantity demanded equals to quantity supplied.

If the demand for the air decreases then the quantity of the air travel will also decrease and thus when the supply and demand change so do the changes associated with the equilibrium prices.

An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only

Pavel [41]

Answer:

vb = 22.13 m/s

Explanation:

ma = 124 kg

mb = 13 kg

vi = 2.10 m/s

According to the property of conservation of momentum, and considering that, initially, both the astronaut and the bag moved together at 2.10 m/s:

$(m_a+m_b)v_i=m_av_a+m_bv_b$

The minimum final velocity of the bag, vb, the will keep the astronaut from drifting away forever occurs when va = 0:

$(124+13)2.10=124*0+13v_b\\v_b=\frac{287.7}{13}\\v_b= 22.13\ m/s$

The minimum final velocity of the bag is 22.13 m/s.

A hall probe serves to measure magnetic field strength. such a probe consists of a poor conductor 0.155 mm thick, whose charge-c

jeka94

We are given the following:
thickness, T = 0.155 mm
charge-carrier density, n = 1.05 x 10^25 / m3
current, I = 2.67 A
voltage, V = 4.89 mV

We are asked to get the magnetic strength, B

To solve this, we use the Hall Effect formula:
V = - IB / neT
where e is the charge of an electron which is e = 1.60 x 10^-19 and B is the magnetic field
Rearranging the formula
B = -V n e T / I
Substituting the given values
B = - (4.89 x 10^-3 V) (1.05 x 10^25 / m3) (0.155 x 10^-3 m) / 2.67 A
B = -2.98 x 10^18 Teslas
