Un coche inicia un viaje de 450 km a las ocho de la mañana con una velocidad media de 90 km/h. ¿A qué hora llegará a su destino?
Answer:
Llegara a su destino a la 1:00 pm
Explanation:
Si el coche va a 90 km/h buscamos un numero q al multiplicarlo por 90 nos de 450. Entonces 90×5 = 450, si hacemos la cuenta desde las ocho de la mañana mas las 5 horas del viaje terminaria llegando a su destino a la 1:00 pm.
3. What is the mass of a falling rock, accelerating at 9.8m/s²?? if it produces a force of 147N? PLEASE HELP!! I WILL GIVE BRAINLEST!!!<3
Answer:
15Explanation:
Formula
Force = mass × acceleration
147N =? × 9.8 ms2
M =
[tex] \frac{147 }{9.8} [/tex]
M = 15
Double Check
15 X 9.8
147N

0.0010 kg pellet is fired at a speed of 52.2 m/s at a motionless 3.3 kg piece of balsa wood. When the pellet
hits the wood, it sticks in the wood and they slide off together. With what speed do they slide? Round your
answer to the nearest thousandth.
m/s
The formula for momentum is p = m*v
The conservation of momentum suggests:
m*vi = m*vf (initial mass times initial velocity = final mass times final velocity or initial momentum = final momentum)
(0.0010)(52.2) = (0.0010 + 3.3)vf
vf = (0.0010)(52.2)/(0.0010 + 3.3) = 0.0522/3.301 ≈ 0.01581 m/s
To the nearest thousandth ≈ .016 m/s

Write as if you are teaching someone about lunar phases!
Write one paragraph about lunar phases, act as if you are teaching a person about these lunar phases.
THANK YOU SOOOO MUCH IF YOU CAN ACTUALLY HELP ME!!
Answer:
so a A lunar phase is an angle of the moon to the earth so it appears differently every day. The moon goes through 8 major phases. A new moon is when the moon cannot be seen because we are looking at the unlit half of the Moon. The new moon phase occurs when the Moon is directly between the Earth and Sun. A solar eclipse can only happen at new moon.

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Dos resistencias de 30 y 20 Ω se conectan en seria a un generador que tiene una diferencia de potencial de 20 V entre sus bornes. a. Determina la resistencia equivalente de la asociación b. Dibuja el circuito y coloca un amperímetro que indique el valor de la intensidad de la corriente y unos voltímetros que muestren la diferencia de potencial entre los extremos de las resistencias ¿Qué valores muestran estos aparatos?
Answer:
V = 12V, V = 8V
Explanation:
a) In this series circuit the equivalent resistance is
Req - R1 + R2
Req = 30 + 20
Eeq = 50 Ω
b) see attached
c) the circuit current is
i = V / Req
i = 20/50
i = 0.4 A
voltages are>
V = 0.4 30
V = 12V
V = 0.4 20
V = 8V
I’m offering 15 points for this 1 multiple choice question. The answer is not D. Pls answer, though I think I know the the answer, but I just want to make sure.
Answer:
I wanna say C
Explanation:
because A would be getting it nowhere and B would just take more time but when you use C it would be the greatest force.
The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?
A. 1/2 m
B. 1 m
C. 2 m
D. 2 seconds
E. none of these
Answer:
Suppose that the wave equation is:
f(x) = A*cos(k*x)
The wave is in phase for two points x₁ and x₂ if:
f(x₁) = f(x₂)
And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:
wavelength = x₂ - x₁
In this case, we know that the wave is in phase for two points that are 2 m apart.
Then we can use the points:
x₁ and x₂ such that:
x₂ = x₁ + 2m
We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.
Then the wavelength will be:
wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m
Then the wavelength is 2m.
The correct option is C.

A king orders a gold crown having a mass of 0.5 kg. When it arrives from the metalsmith, the volume of the crown is found to be 185 cm3. Is the crown made of solid gold?
Answer:
The crown is not made of solid gold.
Explanation:
Density ρ = M/V. M and V are given.
The density of the crown is (0.5 kg)/(185 cm3) * (106 cm3)/(1 m3) = 2.7*103 kg/m3.

g The ant has traveled 10 cm horizontally and 6 cm vertically from its starting point on a twig with a slope of 0.5. If this is the only information the ant has, what function best approximates the geometry of the twig at the point the ant is on? b) The ant can use its model of the environment to plan its movements. In particular, it wants its next step to take it no higher than 0.1 cm above its current location. How far can the ant travel horizontally and still accomplish this?
Answer:
a) a right triangle, b) x = 0.167 m
Explanation:
a) It is asked to find which geometry figure describes the movement of the ant.
Let's use trigonometry with the angles measured in radians
tan θ = y / x
tan θ = 6/10
θ = tan⁻¹ 0.6
θ = 0.54 rad
this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle
b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea
x = 0.1 / tan 0.54
x = 0.1668 m
x = 0.167 m

using a diagram explain how acceleration can be obtained from a velocity time graph
Answer:
For any v-t graph the acceleration is the slope of the graph. For average acceleration in a time period ‘t’ consider the change in velocity in time t and divide it by the time t. For instantaneous acceleration you need to go into the realm of differential calculus.

I lift a 20kg ball up 2.5 meters off the ground on Earth.
-Earth’s gravitational acceleration is about 9.8 m/s2.
How much gravitational potential energy does the ball have at this point? _____________
How much work did I do lifting up the ball? _____________________________________
If I lift the same ball the same distance on the Moon, then how much gravitational potential energy will it have? (Moon’s Gravity = 1.6 m/s2) ____________________________________
Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.
How much work did I do lifting up the ball? As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.
Explain the law of inertia in your own words.
A
An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.
Explanation:
Answer:
Law of inertia is Newton's first law of motion..
Explanation:
It means that a body will tend to be in it's motion or tend to move in a straight line unless any external force is acted upon it..
Eg: while you are travelling in bus.. If breaks are suddenly applied your body falls forward because you were in motion with bus but it tries to be in motion when breaks are applied...
