Answer:
Density = 1.14 kg/mm³
Explanation:
Given the following data;
Volume = 2.10 cm³ to mm = 2.10 * 10 = 21 mm³
Mass = 23.94kg
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
Substituting into the equation, we have;
Density = 1.14 kg/mm³
Answer:
1.52m/s
Explanation:
Using the law of conservation of momentum
m1u1 + m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are the initial velocities
v is the final velocity
Substitute the given values into the formula
0.013(270)+2(130) = (270+130)v
3.51+260 = 400v
263.51 = 400v
v = 400/263.51
v = 1.52m/s
Hence the velocity after the bullet emerges is 1.52m/s
Answer:
-Frontal Lobe
-Medulla Oblangata
Explanation:
-Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. Such areas light up in scans.
-The frontal lobe because it deals with reasoning and thoughts. Also the -
Medulla Oblongata because it is responsible for breathing and heart rate.
