To solve this problem we will apply the concept of Impulse. Which is described as the product between the Force and the change in time. Mathematically this can be described as
Where,
F = Force
= Time
Our values are given as,
F = 1450N
Replacing we have,
Therefore the impulse delivered to the soccer ball is 
or 
Objects with less density than water will float when you put them in water.
Objects with greater density than water will sink when you put them in water.
Answer:
19 cm sq
Explanation:
you have to count one full and half area occupied by leaf in each box, then you have to multiply with 1 cm sq.
Whether a line is "steep" or "shallow" depends on the slope of the line. In the equation y=mx+b, m is the slope. In your first equation, 1/2x+4, the slope would be 1/2 which means there is 1 increase in the vertical, or y, value for each 2 increases in the horizontal, or x value. This line would be shallow.
Answer:
Temperature at which the resistance is twice the resistance at 
is 
Solution:
As per the question:
Temperature coefficient, 
Reference temperature, 
Resistance, 
Now, using the formula:
- Yes, this temperature holds for all all the conductors of copper, irrespective of the size and shape of the conductor.
