Explain how the basic unit are combined to give the derived units of force, velocity, pressure and work
Velocity:
Velocity is change in displacement with respect to time:
[tex]\frac{\Delta x}{\Delta t}[/tex]
Analysing the units, meters (displacement) and seconds (time) are basic units:
[tex]\frac{m}{s}[/tex]
Therefore the unit of velocity is m/s
Force:
Newton's second law of motion:
[tex]F = ma[/tex]
Kilogram (mass) is a basic unit, and accelerations unit can be found using the equation:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
Analysing the units:
[tex]\frac{\frac{m}{s}}{s}=\frac{m}{s^2}[/tex]
Therefore, the unit of force is:
[tex]kg\frac{m}{s^2}[/tex]
Pressure:
Pressure is given by the equation:
[tex]P=\frac{F}{S}[/tex] where S is area of effect, F is force
Area for a basic rectangle (geometric shape is arbitrary for dimensional analysis) is found by multiplying two lengths:
[tex][l^2]=m^2[/tex], the unit of area
Dividing the aforementioned unit of force by the unit of area:
[tex]\frac{kg\frac{m}{s^2}}{m^2}=\frac{kg}{ms^2}[/tex], the unit of pressure
Work:
Work is given by the equation:
[tex]W=\vec{F}\cdot \vec{x}[/tex], (dot product may be assumed as normal multiplication for the purposes of unit analysis)
Knowing displacement's (x) unit is m:
[tex][W]=\frac{kgm}{s^2}m=\frac{kgm^2}{s^2}[/tex], the unit of work.
difference between horizontal and vertical motions
Answer:
This is to say that the vertical velocity changes by 9.8 m/s each second and the horizontal velocity never changes. This is indeed consistent with the fact that there is a vertical force acting upon a projectile but no horizontal force.

if a person with a mass of 70kg is standing on scale in an elevator when the cable snaps, what will the reading on the scale be during free-fall?
Answer:
The reading will be the same.
Explanation:
Mass does not depend upon anything and it remains the same anywhere. What changes is the weight of the body because it depends upon gravity and is different at different places.
Giving me the brainest will be helpful.
The reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.
What is a weighing scale?A weighing scale known as a balance is a device used to quantify weight or mass. The classic scale is made up of two plates or bowls that are suspended at equal distances from a fulcrum.
A person with a mass of 70kg is standing on a scale in an elevator suddenly the cable snaps, The reading on the scale during free-fall will be the same as the initial elevator condition.
Hence the reading on the scale during free-fall will be the same. reading on the scale is independent of the external environment.

Using your knowledge of momentum explain why cars are designed to have crumple zones?
Answer: I think cars are designed to have crumble zone because lets say you're going 60-70 mph and you hit a brick wall that cant move, it would be a very hard jolt causing the beings inside to get thrown forward, but if it has a crumble zone it would slow the the jolt from is slowing down in the hit.
An object is known to have balanced forces on it. Which of the following would be a true statement?
If an object has a balanced force on it, there is a possibility that the object may be in a position i.e. there is no change in speed and direction of the body.
If the forces acting on an object is balanced, it means that the net force acting on the body is zero.
According to Newton's law of motion, an object will continue in a state of motion in a straight line unless acted upon by an external force.
This external force might be a balanced or unbalanced force. Hence if an object has a balanced force on it, there is a possibility that the object may be in a position i.e. there is no change in speed and direction of the body.

why is the saturated lapse rate less than the dry adiabatic lapse rate?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.
Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.

If the mass of an object is 176 and Net force is 50, what would be the Acceleration?
Answer:
0.28m/s²
Explanation:
Force = mass•acceleration
F = m•a
50 = 176•a Divide both sides by 176:
50/176 = a ≈ 0.28 m/s²

Three forces act simultaneously on poin J. One force is 10.0 N north; the second is 15.0 N west; the third is 15.0 N 30.0° east of north. Determine the magnitude and direction of the resultant force.
The magnitude and direction of the resultant force are 10.0N and 101.36⁰
The sum of force along the force horizontal is expressed as:
[tex]\sum F_x=-15.0N+15cos30\\\sum F_x = -15.0N + 12.99N\\\sum F_x = -2.01N[/tex]
The sum of force along the vertical is expressed as:
[tex]\sum F_y = +10N[/tex]
Calculate the magnitude of the force:
[tex]F=\sqrt{(\sum F_x)^2+(\sum F_y)^2} \\F=\sqrt{(-2.01)^2+(10)^2} \\F=\sqrt{104.0401}\\F= 10.2N[/tex]
Hence the magnitude of the resultant force is 10.2N
Find the direction
[tex]\theta = tan^{-1}\frac{y}{x}\\ \theta = tan^{-1}\frac{10}{-2.01}\\\theta =tan^{-1}(-4.9751)\\\theta =-78.63^0\\\theta = 180-78.63 = 101.36^0[/tex]
Hence the magnitude and direction of the resultant force are 10.0N and 101.36⁰

A ball Of Mass. 0.5 kg initially at rest is kick directly toward offense from appoint 20 m away as shown below the velocity of the ball as it leaves the kickers foot is 16 M/S at angle 45 degrees above the horizontal the top of the fence is 4 m high the ball hits nothing Wallen flight and a resistance is negligible the acceleration due to gravity is 9.8 M/S^2 determine the time it takes for the ball to reach the plane of the fence.
Answer:
a. The horizontal component of the velocity is constant so vxt = d where vx = v0 cosθ = 16m/s t = d/v = 2s
b. The height of the ball during its flight is given by y = v0yt + ½ gt2 where v0y = v0sinθ = 12m/s and g = –9.8m/s2 which gives at t = 2s, y = 4.4m. The fence is 2.5m high so the ball passes above the fence by 4.4m – 2.5m = 1.9m
