Ionic bond.
In the ionic bond one atom loses one or more electrons, leaving the atom with positive charge, and the other atom accepts those electrons standing with negative charge.
Explanation :
When a ball is tossed from an upper storey window off a building, the height of the object as a function of time is given by :

Here, u = 8 m/s
The ball strikes at an angle of 20 degrees below the horizontal. We need to find the time taken by the ball to reach a point 10 meters below the level of launching such that, h (t) = 10 m and a = g = 9.8



After solving the above equation, t = 0.855 seconds
So, the ball will take 0.855 seconds to reach a point 10 m below the level of launching. Hence, this is the required solution.
Answer:
This relationship is explained by Ohm's law
Explanation:
Ohm's law states that the current flowing through a circuit or a resistor is directly proportional to the voltage across the resistor and inversely proportional to the resistance. Where current is i, voltage is v and resistance is r, Ohm's law can be represented mathematically as
V= IR
The correct answer is:
false
The explanation:
It is not called a control group as the control group is a group of subjects closely resembling the treatment group in many demographic variables but not receiving the active medication or factor under study and thereby serving as a comparison group when treatment results are evaluated.
Answer:
1 m/s
(i think, *nervous sweat*)
Explanation:
We can tell this by looking at the graph. When t = 8, we will look at the time. We see that when the x (time) is 8, the velocity is 1 m/s.
