Answer:

Explanation:
The equation for the linear impulse is as follows:

where
is impulse,
is the force, and
is the change in time.
The force, according to Newton's second law:

and since 
the force will be:

replacing in the equation for impulse:

we see that
is canceled, so

And according to the problem
,
and the mass of the passenger is
. Thus:



the magnitude of the linear impulse experienced the passenger is 
Answer:
2 0.00130719 m/s
Explanation:
Now we have
7.86 furlongs/fortnight
7.86 x 220 yards / fortnight
1729.2yards / fortnight
1647.8 yards / 14 days
123.5yards / day
So
123.5 x 0.9144 meter / day
112.meters / day
=112.9meters / 86400s
= 0.001307m/s
Answer:
A
Explanation:
Basically all the other answer are opposites like Exercise is an effective way to relieve stress and lots of Stress does have Negative effects on people
Answer:
a. 2500 cm³.
b. 2.5 litres.
Explanation:
Given the following data:
Density = 0.8g/cm³
Mass = 2000g
To find the volume of the petrol;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;

Making volume the subject of formula, we have;
Substituting into the equation, we have:

Volume = 2500 cm³
a. The volume of the petrol in the can in cubic centimeters (cm³) is 2000.
b. The volume of the petrol in the can in litres;
1000 cm³ = 1 litre
2500 cm³ = x litres
Cross-multiplying, we have;
1000x = 2500
x = 2500/1000
x = 2.5 litres.
Therefore, the volume of the petrol in the can in litres is 2.5.
The Earth's magnetic field lines appear to emanate perpendicularly from the poles and go round along the Earth from the South Pole to the North Pole. Therefore, the Earth's magnetic field is generally not parallel to the ground at every location. It is parallel to the earth at the equator near the earth's surface.
The Earth's magnetic field, also known as the geomagnetic field, is a magnetic field that extends from the Earth's interior into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
The magnetic field varies in strength over the earth's surface. It is strongest at the poles and weakest at the equator.
