Answer:
ATP and NADPH
Explanation:
ATP represents the chemical energy that is obtained from light (luminous energy).
NADPH represents the reducing power that will be used to reduce CO2 in the Calvin cycle
Answer:
Average speed = 5 m/s
Explanation:
Given the following data;
Distance = 100m
Time = 20 secs
To find the average speed;
Speed = distance/time
Substituting into the formula, we have;
Speed = 100/20
Speed = 5m/s
Therefore, Elsa's average speed is 5 meters per seconds.
Answer: c) 42 N
Explanation:
M = 2.5 kg
L = 2.5 m
h = L(1 - sin 40 degrees)
Potential energy Mgh = MgL(1 - sin 40 degrees )
kinetic energy = MgL(1 - sin 40 degrees)
(1/2)Mv^2 = MgL(1 - sin 40 deg)
Mv^2 = 2MgL(1 - sin 40 deg)
Fc = Mv^2/L
Fc = 2Mg(1 - sin 40 deg)
= 2 x 2.5 x 9.8 x (1 - sin 40 deg)
Fc = 17.5 N
Let T = tension in the string.
T - Mg = Fc
T - 2.5 x 9.8 = 17.5
T - 24.5 = 17.5
T = 17.5 + 24.5
T = 42 N
Complete Question: A +10 nC charge is located at the origin. What is the electric field at the position (x2,y2)= (-5.0cm, 0cm)? Write electric field vector in component form.
E2x, E2y=? N/C
Answer:
Ex = -3.6*10⁴ N/C Ey=0
Explanation:
As the charge producing the field is positive, the direction of the field, which is the one that would take a positive test charge located in the point of interest, will be away from this point, pointing to the left.
If we choose the positive direction to be to the right, the electric field component along the x-axis will be negative.
The magnitude of the field can be obtained applying the electric field definition, and the Coulomb's Law to the charge in the origin, as follows:
E = k*q/r² = 9*10⁹N*m²/C²*10⁻⁸C/(0.05)² m² = 3.6*10⁴ N/C
As the electric field follows the same line as the electric force, it has only component on the x axis, so:
Ex = -3.6*10⁴ N/C
Ey = 0
In order to make structures more seismic safe there are various ways by which one can build earthquake resistance structures which are far better than conventional ones.
The pyramidal or triangular shape structures contain less number of sides.A structure containing less number of sides frames greater resistance shape.
A rigid structure is more crumble and is more prone to annihilation.So the structure should be flexible.If we compare a taller building with a shorter one,the tall structure is more flexible.The shorter builds can not withstand the force of earth quakes.
During the construction of buildings,one should introduce the foundational plates .The layered foundational plates help buildings or other structures from destruction as they allow the sliding movement of the earth quake.
