Answer:
To convert from denary to binary, start by subtracting the biggest place value you can from the denary number, then place a 1 in that place value column. Next, subtract the second biggest place value you can, and place a 1 in the column. Repeat this process until you reach zero.
You start your bicycle ride at the top of a hill moving East. You coast down the hill at a
constant acceleration of 2 m/s^2. When you get to the bottom of the hill you are moving
18 m/s, and from there you pedal to maintain that velocity for one minute.
a) Draw the velocity vector and why you drew it that way.
b) Draw the acceleration vector and why you drew it that way.
c) How far will you have gone in total from the time you left the hilltop?

What is displacement?
Displacement means when you move something from its original position. Let's say you want to sit on a chair. You move the chair from where it was originally placed. That's displacement.

The weight of an object is 5 N. At a certain instant, its momentum is 6 kg m/s-¹ . Due to a force applied in the direction opposite of motion. the velocity is of the object decreased to 4 m/s-¹ during 4s. What is the force exerted on the object ?
You are riding a jet ski at 75 m/s and notice something in the water ahead of you. It takes you 10
seconds to slow down and come to a stop(0 m/s). What was your average acceleration?
Plz help!!!
Answer:
Im pretty sure its 7.5
Explanation:
your initial ( starting) velocity was 75. Your final velocity was 0. 75 / 0 = 0 m/s.
BUT you are calculating your acceleration, so it would be 75 - 0 divided by 10 = 7.5
if we assume that between birth and 2.5 y of age a child uses 3 diapers per day estimate total number of disposable diapers used per year in the us
Answer:4.38 X 10^10 diapers.
Explanation:
[3 diapers / 1day] X [365 day / year] X 1 year X 40million (rough guess of 1-2.5 year olds) = 4.38 X 10^10 diapers.
if we assume that between birth and 2.5 y of age a child uses 3 diapers per day then the total number of disposable diapers used per year in us would be 1095 diapers
What is multiplication?Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis.
as given in the problem if we assume that between birth and 2.5 y of age a child uses 3 diapers per day
The number of diapers used in a day = 3
as there are 365 days in a year
The total number of diapers used in a year = 3×365
The total number of diapers used in a year = 1095 diapers
Thus, The total number of disposable diapers used in the United States each year would be 1095 diapers if we assume that a child uses 3 diapers per day between birth and 2.5 years of age.

Someone says, “The sun seems brighter because it is bigger than other stars.” What would you say?
Answer:The sun is not a particularly large star. It appears brighter because it is only 93 to 95 million miles away or about 8 light minutes. Whereas the next closest star is 4.5 light years away.

A block having a mass of m = 19.5 kg is suspended via two cables as shown in the figure. The angles shown in the figure are as follows: α = 17° and β = 27°. find the numeric value of the T1 and T2 in new ton?
The equilibrium condition allows finding the result for the tensions of the cables that support the block are:
T₁ = 245.1 N and T₂ = 263.1 N
Newton's second law establishes a relationship between the net force, the mass and the acceleration of the bodies, in the special case that the acceleration is zero is called the equilibrium condition.
∑ F = 0
Where F is the force.
A free body diagram is a diagram of the forces without the details of the bodies, in the attachment we can see a free body diagram of the system.
Let's write the equilibrium condition for each axis.
x-axis
T₂ₓ - T₁ₓ = 0
T₂ₓ = T₁ₓ
y-axis
[tex]T_{1y} + T_{2y} - W =0[/tex]
We use trigonometry to find the components of stress.
cos 17 = [tex]\frac{T_{1x}}{T_1}[/tex]
sin17 = [tex]\frac{T_{1y}}{T_1y}[/tex]
T₁ₓ = T₁ cos 17
[tex]T_1_y[/tex] = T₁ sin 17
cos 27 = [tex]\frac{T_2_x}{T_2}[/tex]
sin27 = [tex]\frac{T_2_y}{T_2}[/tex]
T₂ₓ = T₂ cos 27
[tex]T_{2y}[/tex] = T₂ sin 27
We substitute.
T₂ cos 27 = T₁ cos 17
T₂ sin27 + T₁ sin17 = W
We solve the system.
[tex]T_1 \frac{cos 17 \ sin 27}{cos 27} + T_1 sin 17 = m g \\T_1 ( tan 27 cos 17 + sin 17) = 19.5 \ 9.8[/tex]
T₁ (0.7796) = 191.1
T₁ = 245.1 N
We look for the T₂ tension.
T₂ = [tex]T_1 \ \frac{cos 17 }{cos 27}[/tex]
T₂ = 245.1 [tex]\frac{cos 17}{ cos 27}[/tex]
T₂ = 263.1 N
In conclusion, using the equilibrium condition we can find the result for the tensions of the cables that the block supports are:
T₁ = 245.1 N and T₁ = 263.1 N

Why do bulbs in series circuit glow brightly than those in the parallel circuit?
In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness. In parallel, both bulbs have the same voltage across them.
25. Spider-Man Spider-Man holds the bottom of an elevator with one hand.
With his other hand, he holds a spider cord attached to a 50-kg box of
explosives at the bottom of the cord. Determine the force that the cord
exerts on the box if (a) the elevator is at rest; (b) the elevator accelerates up
at 2.0 m/s2; (c) the upward-moving elevator's speed decreases at a rate of
2.0 m/s2; and (d) the elevator falls freely.
Answer:
Explanation:
a) F = m(g + a) = 50(10 + 0.0) = 500 N
b) F = m(g + a) = 50(10 + 2.0) = 600 N
c) F = m(g + a) = 50(10 - 2.0) = 400 N
d) F = m(g + a) = 50(0.0 + 0.0) = 0.00 N

Forces acting parallel to the ramp with UP RAMP being positive direction.
F = ma
Tension minus weight minus friction will equal mass acceleration
T - mgsinθ - μmgcosθ = ma
T = m(a + g(sinθ + μcosθ))
T = 200(1 + 9.8(sin25 + 0.05cos25))
T = 1,117.14995
Which is closest to answer A.
Understand that answer precision to 3 or 4 significant digits as exampled by our solution options CANNOT be justified by input numbers with only a single significant digit as in this question.
In fact, we cannot get the 1136 N result unless we also use gravity to a single significant digit of 10 m/s²

Identify the energy transformations for a gas fire
Answer:
The release of energy from fuels is used to make other forms of energy. When gasoline burns in a car engine, some of the chemical energy in the gasoline is converted into heat. The heat is converted into mechanical energy. The mechanical energy moves the car.
