Answer:
Materials which do conduct electricity, like copper, are called conductors. In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.
I hope it helped you...
The imaginary line from the tip of the football to the football to the sideline is called Line of Scrimmage. I believe.
Answer:
In an earthquake prone area, the things that are needed to be considered for the buildings to stand constant and no cause of damages are as follows-
- The foundation of the building must be made strong, using large amount of concretes so that it can hold the entire load of the building.
- The pillars of the buildings are also should be firmed, rigid, strong and thick.
- The buildings are needed to be construct in such a way that during any seismic event, the forces can be redistributed easily through the body of the building without causing any damage.
- The buildings must be overall comprised of holding high strength and stiffness.
To test a food for starch, you can add a few droplets of iodine to it, if the liquid changes to a blue/black color then starch is present. To test for sugar you can use Benedict's solution, which will also have a color change from blue to yellow/red/orange. Add Biuret Reagent solution to test for protein, the solution will turn a pink or purple color... Note that this may not improve the taste or color of your gingerbread biscuit though :)
Answer:
Force will be acting southward and the magnitude of force will be 1000 N
Explanation:
given,
mass of car = 1000 Kg
initial speed of the car (u) = 20 m/s
final speed of the car (v) = 0 m/s
distance to stop the car = 200 m
using equation of motion
v² = u² + 2 a s
0 = 20² + 2 x a x 200
400 a = -400
a = -1 m/s²
Now, we know
Force = mass x acceleration
F = 1000 x -1
F = -1000 N
- ve sign of force represent force will be acting in the opposite direction of motion.
Force will be acting southward and the magnitude of force will be 1000 N
