the weight of the space probe on that planet is 50 N

To calculate the weight of the space probe, we use the formula below.

Formula:

  • W = mg

Where:

  • W = weight of the space probe on the planet
  • m = mass of the space probe
  • g = acceleration due to gravity.

From the question,

Given:

  • m = 25 kg
  • a = 2 m/s

Substitute these values into equation 1

  • W = 25(2)
  • W = 50 N.

Hence, the weight of the space probe on that planet is 50 N

An ant carries a morsel of food 4.26 meters along a straight path to his nest. He then turns around and follows the path back to
Basile [38]
The displacement is zero. The most important concept to understand is the difference between displacement and total distance traveled. Total distance traveled would be tracking the length of the entire path the ant walked for the whole time (4.26m x 2). Displacement is how far from a designated origin (here, the food source) the ant ended up at the end of the time. Mathematically, the ant walked 4.26m from food source to nest (+4.26m) and then walked from the nest to food source (-4.26m), so the net displacement is [+4.26] + [-4.26] = 0m.

Use the Inverse square law, Intensity (I)<span> of a light </span>is inversely proportional to the square of the distance(d).

I=1/(d*d)

Let Intensity for lamp 1 is L1 distance be D1 so on, L2 D2 for Intensity for lamp 2 and its distance.

L1/L2=(D2*D2)/(D1*D1)

L1/15=(200*200)/(400*400)

A baseball bat changes the momentum of a ball with an impulse of 13.8 Nᐧs. What is the average force that the bat exerts on the
vladimir2022 [97]

Answer:

13800 N

Explanation:

Impulse is the product of average force and time expressed as I=Ft where I is the impulse which results into change in momentum, F is the average force and t is the time of impact. Making F the subject of formula then

F=\frac {I}{t}

Substituting I with 13.8 N.s and time, t witg 0.001 s then the average force is calculated as

F=\frac {13.8 N.s}{0.001}=13800N

Therefore, the average force is equivalent to 13800 N

A 0.15 kg baseball is hit by a baseball bat. Right before it is hit, the ball’s speed is 30 m/s, and right after it is hit, the
Roman55 [17]

Answer:

Impulse will be 12 kgm/sec

So option (b) will be correct option

Explanation:

We have given mass of the baseball m = 0.15 kg

Ball speed before hit v_1=30m/sec

Ball speed after hitting  v_2=-50m/sec ( negative direction due to opposite direction )

We have to find the impulse

We know that impulse is equal; to the change in momentum

So change in momentum = m(v_1-v_2)=0.15(30-(-50))=0.15\times 80=12kgm/sec

So option (b) will be correct option
