Answer:
If jack is in the piece of furniture it would submerge.
Explanation:
The piece of furniture would submerge if the weight applied on the furniture is greater than the maximum buoancy force the water can provide.
maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.
= 
v = area × thickness of pine
= 0.075 
therefore buoancy force = 1025×0.075×9.8 N
= 753.375 N
weight of rose alone = 46×9.8 N = 450.8 N
weight of jack alone = 58×9.8 = 568.4 N
weight of pine = density of pine × volume of pine
= 350 × 0.075= 26.25 N
weight of pine + weight of rose = 450.8+26.25=477.05 N
weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N
therefore if jack is in the piece of furniture it would submerge.
Answer:
C. 9.9 cm
Explanation:
The location of the object, u = 14 cm
The location of the image, v = 5.8 cm
The focal length of the mirror, f = Required
The mirror formula for a convex mirror is given as follows;
Therefore, we get;
Therefore;
The focal length of the mirror, f ≈ 9.9 cm
Answer:
Einsteins theory about time says:
Time slows down or speeds up depending on how fast you move relative to something else (So when I'm having fun time move fast, and when I'm doing my homework, time moves slow :( )
Explanation:
Have a great summer :)
Answer:
Average around 75
Explanation:
It's the average age. You don't really always die of old age but it is 75 years of age.
Force = mass x acceleration
Here we have mass and a force so we are solving for acceleration:
Isolate for acceleration in the equation
Force / mass = acceleration
Fill in the equation:
250 / 70 = acceleration
Acceleration = 3.57 m/s^2
