Given is a lunar probe is moving 1670 m/s at a 73° angle. it needs to land on the moon  3.71 x 10⁸ m away in a 46° direction in 8.64 x 10⁴ s.

The initial velocity will be

1670 x cos (73°-46°) = 1487.981 m/s

Using the second equation of motion, we have

s = ut + 1/2 at²

The final velocity will be zero after landing on Moon.

Substituting the values, we have

3.71 x 10⁸=  1487.981 x  8.64 x 10⁴ + 1/2 a ( 8.64 x 10⁴)²

Solving the equation, we get

acceleration, a = 0.065 m/s²

Thus, the magnitude of the acceleration that the engine must produce is   0.065 m/s²

The friend who has the greater displacement is the one who takes the longest path.

The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.

Given, two friends leave a movie theater and take different buses to the same ice cream shop. One bus takes a longer route driving on a high-speed highway, while the other takes a shorter route on lower-speed local roads.

The resistance of the unknown resistor is determined as 0.39 ohms.

The total resistance of the circuit is calculated as follows;

V = IR

R = V/I

R = (3.5)/10

R = 0.35 ohms

The resistors are in parallel arrangement

1/R = 1/R₁ + 1/R₂ + 1/R₃

1/0.35 = 1/5 + 1/10 + 1/R₃

100/35 = 3/10 +  1/R₃

20/7 = 3/10 +  1/R₃

1/R₃ = 20/7 - 3/10

1/R₃ = (200 - 21)/70

To find:

The new volume of the gas after the pressure increases to 2.2 atm.

___

steps

⇒ [tex]V_1P_1=V_2P_2[/tex]

⇒ [tex](550\text{ml})(1.8\text{atm})[/tex]

⇒ [tex]=(x)(2.2\text{atm})[/tex]

⇒ [tex]x=\frac{(550)(1.8)}{2.2}[/tex]

⇒ [tex]x=450\text{ml}[/tex]

Answer:

V₂ = 450 mL

Explanation:

Because you are dealing solely with pressure and volume, you can use Boyle's Law to find the missing value. The equation looks like this:

P₁V₁ = P₂V₂

In this formula, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You have been given values for all of the variables except for "V₂". Thus, you can substitute the given values into the equation and simplify to find the answer. The final answer should have 2 sig figs to match the given values.

P₁ = 1.8 atm                      V₁ = 550 mL

P₂ = 2.2 atm                     V₂ = ?

P₁V₁ = P₂V₂                                               <----- Boyle's Law equation

(1.8 atm)(550 mL) = (2.2 atm)V₂              <----- Plug given values in

990 = (2.2 atm)V₂                                    <----- Multiply 1.8 and 550

450 = V₂                                                  <----- Divide both sides by 2.2

Step-by-step explanation:      

Step 1: Formula

10.0 = Meters

800 = Newtons

4.0 = Centre of Gravity

Explanation in words (Short Form)

-  We know all the formulas and that we are calculating the least force being applied. We know that balancing the pole at (A) with the weight of the gravity will equal more force at B times 10. So the answer will be 320 N because the B force will equal 3200. If we divide 3200 by 10. The answer will result as 320. So the final answer for this question is 320N

Answer:  

Balancing the pole at A with the weight acting at the centre of gravity = 800(4) Force at B multiplied by 10 = 3200 divided by 10 equals 320N
