Answer:
<h2>500 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula

where
m is the mass
v is the velocity
From the question
m = 1.6 kg
v = 25 m/s
We have

We have the final answer as
<h3>500 J </h3>
Hope this helps you
Answer:
direct
Explanation:
the more dense it is the more pressure it will exert
Answer:
65.2L
Explanation:
Using the general gas equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (Kelvin)
According to the information provided in this question,
P = 1.631 atm
V = ?
n = 4.3 moles
T = 28°C = 28 + 273 = 301K
Using PV = nRT
V = nRT/P
V = 4.3 × 0.0821 × 301 ÷ 1.631
V = 106.26 ÷ 1.631
V = 65.15
Volume of the gas = 65.2L
