Answer:
5 percent = normal matter
68 percent = dark energy
27 percent = dark matter
Explanation:
Answer:
3.96 meters / sec
Explanation:
The skaters Kinetic Energy is converted to Potential Energy ( ignoring friction)
KE = PE
1/2 * 55 * v^2 = 55 * 9.81 * .8
solve for v = 3.96 m/s
Answer:
Net force = 10N
Explanation:
Net force refers to the sum total of all the forces acting on an object. Net force is denoted by Fnet. According to Newton's third law of motion, for every action force, there is an equal and opposite reaction force. This means that an object with net force is an unbalanced force.
In this case, a wagon is pulled to the right using a force of 20 N and to the left (opposite direction) using a force of 30 N. This means that the net force will be the difference of the two forces acting on the object i.e
Fnet = Fa - Fb
Fnet = 30N - 20N
Fnet = 10N
kilograms per mere cubed ...kgm^-3
Given that,
Depth of seawater, h = 11,033 m
Density seawater, p (rho) = 1025 kg/m³
Gauge Pressure , P = ??
Since, we know that:
Pressure, P = pgh
Pressure = 1025 * 9.81 * 11033
Pressure = 1109395723.3 N/m²
or
Pressure = 1.1 x 10∧8 Pascal
