Answer:
10⁴ Pa
Explanation:
When the tank is half filled ,
- Volume = 5m * 4m * 1m = 20m³
Also we know that ,
- Density of water = 10³ kg/ m³
Density = Mass/Volume
10³ kg/m³ = m/20m³
m = 2 * 10⁴ kg
So that ,
Weight = mg
F = 2*10⁴ × 10 N
F = 2 * 10⁵ N
And ,
Pressure = Force/Area
P = 2 *10⁵/ 5 * 4 Pa
P = 10⁴ Pa
Work = Force multiplied by the distance(or displacement)
Answer:
14 cm
Explanation:
F = (frac{uv}{u – v})
F = +ve
v = -ve
30 = (frac {25 {times} (-v)}{25 – (-v)})
v = (frac {25 {times} (-v)}{25+v})
v = 14cm
(Note that either negative or positive values go to show the positioning and hence, they are not a strong necessity in your final answer.)
So happy that i could help you!
Now this question could turn out to be easy for you!!
Answer:
Explanation:
String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. String theory also requires six or seven extra dimensions of space, and it contains ways of relating large extra dimensions to small ones. In statistical mechanics, entropy is an extensive property of a thermodynamic system. It quantifies the number Ω of microscopic configurations that are consistent with the macroscopic quantities that characterize the system theyre related It later developed into superstring theory, which posits a connection called supersymmetry between bosons and the class of particles called fermions. Five consistent versions of superstring theory were developed before it was conjectured in the mid-1990s that they were all different limiting cases of a single theory in 11 dimensions known as M-theory. In late 1997, theorists discovered an important relationship called the AdS/CFT correspondence, which relates string theory to another type of physical theory called a quantum field theory.
