Answer:
The density will decrease over time
Explanation:
It is like when you cut cheese and leave it out for a day of two it is crusty on the outside but when you cut it in half and leave it out for the same amout of time it is even crustier than the whole one.
Hope this helps
please tell me if I'm wrong and i will try to correct my answer
The work that you do on the lever will be the same as the work done by the lever on the rock. This aligns with the Law of the Conservation of Energy which states that energy can not be created nor destroyed. Since work can be calculated as force applied over a distance, you will apply a smaller force but your distance will be longer. The lever will apply a greater force over a shorter distance in proportion to yours. Therefore, the same amount of work is done on both sides of the lever.
Answer:
To make an inference what needs to be in the text in the order for you is explained below in complete details.
Explanation:
Making an inference requires using what you recognize to guess what you don't understand or understanding between the series. Scholars who make inferences use the evidence in the text along with their own practices to encourage them to figure out what is not straight said, making the text special and remarkable.
Answer:
77.3J
Explanation:
Given parameters:
Mass of the bullet = 50g = 0.05kg
Velocity of the bullet = 200km/hr
Unknown:
Kinetic energy of the bullet = ?
Solution:
Kinetic energy is the energy due to motion of a body.
It is mathematically expressed as;
K.E =
m v²
m is the mass
v is the velocity
we need to convert the velocity to m/s
200km/hr is 55.6m/s
Input the parameters and solve;
K.E =
x 0.05 x 55.6² = 77.3J
Answer:
Radius = 0.8235 cm
Density = 0.7265 g/mL
Explanation:
Given that the volume = 2.34 cm³
The volume of the sphere = 
Thus,



<u>r = 0.8235 cm</u>
Volume = 2.34 cm³ = 2.34 mL (1 cm³ = 1 mL)
Mass = 1.7 g
<u>Density = Mass/ Volume = 1.7 g / 2.34 mL = 0.7265 g/mL</u>
