Find the acceleration due to gravity on the surface of Mars. The

Physics
1 answer:
vampirchik [111]3 years ago
3 0

Answer:

The acceleration due to gravity on the surface of Mars is approximately 3.773 m/s²

Explanation:

The given parameters for Mars with guidance from online search are;

The mass, m = 6.42 × 10²³ kg

The given radius of Mars, r = 3,370 km = 3,370,000 m

The gravitational constant, G = 6.674 × 10⁻¹¹ N·m²/kg²

Therefore, we have, the acceleration due to gravity on the surface of Mars, g_{Mars} given as follows;

g_{Mars} = G × m/r² = 6.674 × 10⁻¹¹ × 6.42 × 10²³/(3,370,000)² ≈ 3.773

The acceleration due to gravity on the surface of Mars, g_{Mars} ≈ 3.773 m/s².

Tea gets cool beacuse of heat tranfer through convenction
Heat transfers from a area of hot region to cold.
The tea is hot in this case, due to taht factor the heat will move towards teh cooler region which is coke and will make the coke warm

Two light bulbs have resistances of 400 Ω and 800 ΩThe two light bulbs are connected in series across a 120- V line. Find the cu
Natasha2012 [34]

1) Current in each bulb: 0.1 A

The two light bulbs are connected in series, this means that their equivalent resistance is just the sum of the two resistances:

R_{eq}=R_1 + R_2 = 400 \Omega + 800 \Omega=1200 \Omega

And so, the current through the circuit is (using Ohm's law):

I=\frac{V}{R_{eq}}=\frac{120 V}{1200 \Omega}=0.1 A

And since the two bulbs are connected in series, the current through each bulb is the same.

2) 4 W and 8 W

The power dissipated by each bulb is given by the formula:

P=I^2 R

where I is the current and R is the resistance.

For the first bulb:

P_1 = (0.1 A)^2 (400 \Omega)=4 W

For the second bulb:

P_1 = (0.1 A)^2 (800 \Omega)=8 W

3) 12 W

The total power dissipated in both bulbs is simply the sum of the power dissipated by each bulb, so:

P_{tot} = P_1 + P_2 = 4 W + 8 W=12 W

Changes in behavior of managers, coworkers, and subordinates can be a warning sign before a layoff. True or false
Yakvenalex [24]

Answer:

The correct answer is - true.

Explanation:

Changes in the higher authorities or managers or coworkers can be a warning sign before a layoff, however, a company or organization needs to give an official notice before a particular time period before the layoff.

The layoff is a temporary suspension or permanent termination from the employment of an employee due to reasons related to business such as reducing manpower or staff and less work in the organization. These reasons can lead to a change in the behavior of the managers, coworkers, and subordinates.
