Answer:
60°
Explanation:
Formula
360/n (if the number is an odd number) or
360/n-1 (if the number is even) (to arrive at an odd number)
SO. 5 is an odd number but not a multiple of 360, so we will use 6 an even number.
360/60-1
360/60=6 images
6-1 =5 images
Thus. the images formed will be 5.
Answer:
1890J
Explanation:
375+45 = 420kg (total mass)
kinetic energy = 1/2 × mass × velocity²
1/2 × 420 × 3² = 1890J
Answer:
The leaf cells would be unable to convert the sun's energy to make food.
Explanation:
The chloroplast in the leaf are used to make food for the plant. If the leaf loses its chloroplast, the leaf with not be able to use solar energy to manufacture their food.
- During photosynthesis, green plants manufacture their food.
- They use sunlight to cause a reaction between carbon dioxide and water.
- The sunlight is trapped using chlorophyll present in the leaf.
- In the absence of the chlorophyll contained in the chloroplast, no solar energy would be generated to cause the reaction to take place.
Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.

Answer:
σ =4.180×10^{-9} C/m^2
Explanation:
electric field due to non conducting sheet is
the force acting on the piece of Styrofoam
Eq= mg
⇒E= mg/q
now,
⇒
charge per unit area (in C/m2) on the plastic sheet σ =4.180×10^{-9} C/m^2
