Answer:
The total displacement from the starting point is 1.5 m.
Explanation:
You need to sum and substract, depending on the movement (to the right, sum; to the left, substract).
First, it moves 4.3 m right and return 1.1 m. So the new distance from the starting point is 3.2 m.
Second, it moves 6.3 m right, so the new distance is 9.5 m.
Finally it moves 8 m to the left, so 9.5 m - 8 m= 1.5 m.
Summarizing, at the end the squirrel is 1.5 m from its starting point.

Answer:
Approximately 
.
Assumption: air resistance on the rocket is negligible. Take 
.
Explanation:
By Newton's Second Law of Motion, the acceleration of the rocket is proportional to the net force on it.
.
Note that in this case, the uppercase letter 
in the units stands for "mega-", which is the same as 
times the unit that follows. For example, 
, while 
.
Convert the mass of the rocket and the thrust of its engines to SI standard units:
- The standard unit for mass is kilograms:
. - The standard for forces (including thrust) is Newtons:
.
At launch, the velocity of the rocket would be pretty low. Hence, compared to thrust and weight, the air resistance on the rocket would be pretty negligible. The two main forces that contribute to the net force of the rocket would be:
- Thrust (which is supposed to go upwards), and
- Weight (downwards due to gravity.)
The thrust on the rocket is already known to be 
. Since the rocket is quite close to the ground, the gravitational acceleration on it should be approximately 
. Hence, the weight on the rocket would be approximately 
.
The magnitude of the net force on the rocket would be
.
Apply the formula to find the net force on the rocket. To make sure that the output (acceleration) is in SI units (meters-per-second,) make sure that the inputs (net force and mass) are also in SI units (Newtons for net force and kilograms for mass.)

The Rinne and Weber tests are frequently used to detect conductive and sensorineural deafness.
Another test to assess conductive and sensorineural hearing impairments is the Weber test. When sound waves cannot flow from the middle ear to the inner ear, conductive hearing loss results.
This may be brought on by issues with the eardrum, middle ear, or ear canal, such as an infection. A helpful, quick, and easy screening test for determining hearing loss is the Weber test.
The test can identify unilateral sensorineural and conductive hearing loss. Conduction hearing is mediated by the middle and outer ear. A tuning fork is used in the Weber test, a hearing screening procedure. It can identify unilateral sensorineural hearing loss and unilateral conductive hearing loss in the middle ear.

Imagine a skinny straw in the water, standing right over the hole. The WEIGHT of the water in that straw is the force on the tape. Now, the volume of water in the straw is (1 mm^2) times (20 cm). Once you have the volume, you can use the density and gravity to find the weight. And THAT's the force on the tape. If the tape can't hold that force, then it peels off and the water runs out through the hole. /// This is a pretty hard problem, because it involved mm^2, cm, and m^3. You have to be very very very careful with your units as you work through this one. If you've been struggling with it, I'm almost sure the problem is the units.
