Answer:
31.2m/s
Explanation:
final velocity = initial velocity + acceleration • time
final velocity = 0 m/s + 6.58m/s/s • 4.74 s
final velocity = 31.2 m/s
Answer:
a = 6.1 m / s²
Explanation:
For this kinematics exercise, to solve the exercise we must set a reference system, we place it in the initial position of the fastest vehicle
Let's find the relative initial velocity of the two vehicles
v₀ = v₀₂ - v₀₁
v₀ = 25.4 - 13.6
v₀ = 11.8 m / s
the fastest vehicle
x = v₀ t + ½ a t²
The faster vehicle has an initial speed relative to the slower vehicle, therefore it is as if the slower vehicle were stopped, so the distance that must be traveled in a fast vehicle to reach this position is
x = 11.4 m
let's use the expression
v² = v₀² - 2 a x
how the vehicle stops v = 0
a = v₀² / 2x
a = 
a = 6.1 m / s²
this velocity is directed to the left
Answer: a= -1.9 m/s²
Explanation: F = ma and a = F / m = 60 N / 32 kg = 1.875 m/s²
Because of law of action and reaction, wall applies same force to dino
In opposite direction and Dino is decelerating. Thus sign Is negative.
Answer:
Each part of a two-dimensional vector is known as a component. The components of a vector depict the influence of that vector in a given direction. The components of a vector depict the influence of that vector in a given direction.

Increased lamp voltage is achieved by turning the light intensity dial.
To enlarge the diameter of the hole and let more light through the slide, the iris diaphragm was modified.
Condenser: Position it higher and closer to the slide's bottom to better direct light to the centre of the slide.

How do you adjust the light level on a microscope?</h3>
Utilize the brightness adjustment knob to change the brightness. Turn the brightness control knob while looking through the eyepieces to make sure there is no glare in the field of view.
Use a daylight balancing filter if your compound microscope has a certain sort of illumination. It typically rests directly on top of the luminator or in a filter holder above the light. This filter is blue.
The daylight balancing filter will correct the colour temperature and produce a higher-quality image if your microscope is lighted by tungsten or halogen (and a better colour image). This blue filter is not necessary if your microscope is an LED.
