The velocity of a vehicle reaches 4 m/s in 4 seconds. Is the velocity of the
car uniform? Explain.
Answers
Answer:
The velocity is not uniform
Explanation:
The velocity is not uniform, since the vehicle is increasing its speed to a value of 4 [m/s] in a time of 4 [s], that is, the vehicle is accelerating to increase its velocity, so when there is acceleration the velocity can not be constant or uniform.
Vf = Vo +(a*t)
where:
Vf = final velocity = 4 [m/s]
Vo = initial velocity = 0
a = acceleration [m/s²]
t = time = 4 [s]
a = (4 - 0)/4
a = 1 [m/s²]
You travel 50 meters at an angle of 37° North of East.
a) Calculate the Horizontal component.
Answers
Answer:
a) x = 39.9 m
Explanation:
To find the components of a vector we can use trigonometric relationships. Since they indicate that the angle is 37º north of east, this angle is measured counterclockwise from the x-axis, therefore using trigonometry.
cos θ = x / d
sin θ = y / d
where the angle is 37º and the distance d = 50 m
x = d cos θ
y = d sim θ
let's calculate
x = 50 cos 37
y = 50 sin 37
x = 39.9 m
y = 30.1 m

An escaped convict runs 1.70 km due East of the prison. He then runs due North to a friend's house. If the magnitude of the convict's total displacement vector is 2.50 km, what is the direction of his total displacement vector with respect to due East?
Answers
Answer:
The right approach will be "47° north of east".
Explanation:
The given values are:
East of prison
= 1.70 km
Displacement vector
= 2.50 km
Now,
The direction will be:
⇒ [tex]Cos \ \theta =\frac{1.7}{2.5}[/tex]
⇒ [tex]=0.68[/tex]
⇒ [tex]\theta=47.16^{\circ}[/tex]
i,e., [tex]\theta = 47^{\circ}[/tex] (north of east)
The direction of his total displacement vector with respect to due East is 1.83km
Resultant vectorGiven the following parameters
Distance ran through east = 1.70km
displacement = 2.50km
Required
Total displacement vector with respect to due north
Using the expression below;
d = √x² + y²
2.5² = 1.7² + y²
y² = 2.5² - 1.7²
y² = 3.36
y = 1.83km
Hence the direction of his total displacement vector with respect to due East is 1.83km

Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, what is the minimum horizontal velocity a diver must have to clear them?
Answers
Answer:6.5 m/s
Explanation:Look at the image I believe that's the answer
The horizontal velocity of the diver would be 6.522 meters / seconds.
What are the three equations of motion?There are three equations of motion given by Newton
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
As given in the problem, Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, then we have to find out the minimum horizontal velocity a diver must have to clear them,
By using the second equation of motion in the vertical direction,
s = ut + 0.5at²
61 = 0+ 0.5×(-9.81) ×t²
t² = 61/(0.5×9.81)
= 12.43
t = 3.526 seconds
The horizontal velocity of the diver = 23 meters / 3.526 seconds
=6.522 meters / seconds
Thus, the horizontal velocity of the diver would be 6.522 meters/second.

An object is dropped from 20. meters above the moon. The acceleration due to gravity on the moon is 1.62 m/s^2
a. How long does it take for the object to impact the moon?
b. At what speed does it impact the moon?
Answers
Answer:
a. Approximately 3.21 seconds
b. Approximately 5.196 m/s
Explanation:
a. The height from which the object is dropped = 20 meters
The location of the occurrence = The moon
The acceleration due to gravity on the moon = 1.62 m/s²
The time it took the object to to impact the moon is given by the equation of free fall as follows;
h = 1/2·a·t²
Where;
h =The height from which the object is allowed to freely fall = 20 meters
a = The acceleration due to gravity on the moon = 1.62 m/s²
t = The time of motion of the object
Substituting the values, gives;
20 = 1/2 × 1.62 × t²
t² = 20/(1.2 × 1.62) ≈ 10.23 s²
t = √ 10.23 ≈ 3.21 s
The time in motion of the object before impact, t = 3.21 seconds
b. The final speed, v is given from the equation for speed under free fall, which is presented as follows;
v = u + a·t
Where
u = The initial vertical velocity = 0
Substituting the values gives;
v = 0 + 1.62 × 3.21 ≈ 5.196 m/s
The final speed, v with which the object impacts the moon ≈ 5.196 m/s

suppose you increase the voltage in the coils of the solenoid of an electromagnet. what happens the the electromagnet?
A. its strength becomes less
B. its strength decreases then increases
C. its strength becomes greater
D. its strength remains the same
Answers
Answer:
Its strength becomes greater
Explanation:
Suppose you increase the voltage in the coils of the solenoid of an electromagnet. the electromagnet strength becomes greater. Hence option C is correct.
What is Electromagnet ?An electromagnet is a type of magnet where an electric current creates the magnetic field. The wire that makes up an electromagnet is often twisted into a coil. A magnetic field is produced by a current flowing through the wire and is focused in the hole in the centre of the coil. When the current is cut off, the magnetic field vanishes. In order to create a stronger magnet, the turns of the wire are frequently twisted around a magnetic core composed of a ferromagnetic or ferrimagnetic material, such as iron.
An electromagnet's key benefit over a permanent magnet is the ability to swiftly alter the magnetic field by adjusting the amount of electric current flowing through the winding. Contrary to a permanent magnet, however

List 2 examples of physical properties that don't
change if the sample size changes.
Answers
Answer:
Temperature, density
Explanation:
Physical properties of a substance are those properties that do not change the chemical composition of the substance. There are two types of physical properties namely: intensive property and extensive property.
Intensive properties are those physical properties that does not depend on the sample size of the substance involved. Examples of intensive physical properties are temperature, density, boiling point. For example, the size or amount of a substance does not determine the the TEMPERATURE or BOILING POINT of the substance.
If the distance of an object is determined from the relation: d = a X + b Y Where: (d) is the distance covered by the body. (a) is a physical quantity which has a dimensions (L T^-1). (b) Is a physical quantity which has a dimensions (L T^-2). So: *
The dimension formula of (X) is T and that of (Y) is T^2.
The dimension formula of (X) is T and that of (Y) is T^-2
The dimension formula of (X) is T^-1 and that of (Y) is T^2.
The dimension formula of (X) is T^-1 and that of (Y) is T^-2.
