Answer:
Gases have three characteristic properties: 1. they are easy to compress, 2. they expand to fill their containers, and 3.they occupy far more space than the liquids or solids from which they form. Compressibility. An internal combustion engine provides a good example of the ease with which gases can be compressed.

Answer:
Explanation:
Same numbers of protons but different number of neutron so i would go for A same atomic number different number of neutrons
Answer:
the ball is rolling 7m/s
Explanation:
Formula for kinetic energy: 1/2mv²
K = 1/2mv²
98 = 1/2(4)v²
98 = 2v²
49 = v²
√49 = v
7 = v
The net torque on the seesaw is 294 Nm.
<h3>What is torque?</h3>
Torque is the force that tends to rotate the body to which it was applied.
To calculate the net torque, we use the formula below
Formula:
- τ = mgd-m'gd'........... Equation 1
Where:
- m = Jenny's mass
- m' = Tom's mass
- d = Jenny's distance from the pivot
- d' = Tom's distance from the pivot
- g = acceleration due to gravity
From the question,
Given:
- m = 40 kg
- m' = 30 kg
- d = 1.5 m
- d' = 1 m
- g = 9.8 m/s²
Substitute these values into equation 1
- τ = (40×1.5×9.8)-(30×1×9.8)
- τ = 588-294
- τ = 294 Nm
Hence, The net torque on the seesaw is 294 Nm.
