Answer:
K.E = 120 Joules.
Explanation:
<u>Given the following data;</u>
Mass = 0.15kg
Distance = 1m
Velocity = 40m/s
To find kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
- K.E represents kinetic energy measured in Joules.
- M represents mass measured in kilograms.
- V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
<em>K.E = 120 Joules.</em>
<em>Therefore, the kinetic energy of the baseball is 120 Joules. </em>
Answer:
Answer 3: When a balloon goes up higher in the air, its size will increase. Since there's less air in the upper atmosphere, there's less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand
Answer: C
Explanation:
As the balloon rises, the gas inside the balloon expands because the atmospheric pressure surrounding the balloon drops. The atmosphere is 100 to 200 times less dense at the float altitudes than on the ground. and as the air is heated inside the balloon it causes it to rise upwards (because it is lighter than the cooler air on the outside). When the pilot needs to bring the balloon down again, he simply reduces the temperature of the air inside the balloon causing it to slowly descend.
Answer:
it's all around you and it can't be destroyed
Sometimes in the same direction but most of them go in the opposite direction
<span>Од сила е еднаква на масата * aceleration
Ние го имаме тоа сила = 5N, маса = 0.6kg a =?
5 = 0,6 * a.
Затоа a = 5 / 0,6
a = 8.33m / s²
