A. in areas farther away from water
Answer:
A time that is less than half an hour
Explanation:
it says velocity is positive so it would yield to a negative acceleration
Answer:
1.1 x 10⁻⁵m³
Explanation:
Given parameters:
Weight in air = 11.29N
Weight in water = 9.190N
Density of gold = 19320kg/m³
Unknown:
Volume of the secret cavity = ?
Solution:
To solve this problem, we need to find the mass of the secret cavity.
Weight of the cavity = Weight of sculpture in air - Weight of sculpture in water
Weight of cavity = 11.29N - 9.190N = 2.1N
Weight = mass x acceleration due to gravity
Mass = = 0.2kg
So;
Volume of substance can be determined from the density.
Density =
Volume =
Now insert the parameters and solve;
Volume = = 1.1 x 10⁻⁵m³
Answer:
Explanation:
Given
Potential Energy of a particle is given by
For minimum or maximum Potential Energy differentiate U(x) w.r.t x
putting
To know minimum value check
at x=-2
so at x=-2 potential energy is minimum
