Answer:
The ratio is 1:1
Explanation:
Firstly we are told the in (a) we have a force which A given to be: FA
We are then told the are two other forces which a B and C which are equal.
These forces are given to be F and 19.5° away from A.
We are then told that the force on the elephant is now three times, of what it was when we only had force A.
Since we are told that B and C are eqaula.
If we say FA = 2N
Then in order for it to be three times, we would have to add 4N since it was the only force present at the time.
If we add two equal forces, then we can devide that 4 by 2.
We then find out that F =2N
and thus equal to FA.
Therefore the ratio of F/FA is
!:1
Answer:
221.17 kJ
Explanation: Note the heat of vaporization is in kJ/mol,then to determine the number of moles of water: divide the mass by 18. Then multiply the number of moles by the molar heat of vaporization of water.
N = 97.6 ÷ 18
Q=molar heat *moles
Q = (40.79) * (97.6 ÷ 18)
This is approximately 221.17 kJ
Answer:
The smaller ball (the tennis ball) will receive a much larger acceleration than the soccer ball of larger mass.
According to Newton's 2nd Law of motion, (force equals mass times the acceleration imparted)
Since in this case we have the same force (50 N) applied to two different masses (one the tennis ball "m" which has smaller mass than the soccer ball of mass "M"), then the resultant accelerations will be different being the acceleration of the tennis ball () much larger than the acceleration imparted to the soccer ball (), as can be seen from solving for the acceleration in the previous equation:
(3 x 10⁸ meter/sec) x (100 cm/meter) x (3.2 x 10⁷ sec/year)
= (3 x 10⁸ x 100 x 3.2 x 10⁷) (meter-cm-sec) / (sec-meter-yr)
= <span>( 9.6 x 10¹⁷ ) ( cm/yr )</span>
