A car accelerates from rest at 6.6 m/s^2. How much time does it need to attain a speed of 7 m/s?
explanation:
Here,
initial velocity(u)=0m/sfinal velocity (v)=7m/sacceleration (a)=6.6m/s²time(t)=?Using Formula;
v = u + at
or, 7 = 0 + (6.6*t)
or, 7 = 6.6t
or 7/6.6 = t
or, t = 1.06s

A student conducts an experiment to test how the temperature affects the amount of sugar that can dissolve in water. In the experiment, she uses 100 milliliters of water in each trial and stirs for five minutes each time.
What is the independent variable in this experiment?
A. the amount of water
B. the temperature of the water
C. the amount of sugar
When dropped from rest, any object will fall a total distance of 19.6 m in the first 2 seconds of its fall. How far
does the object fall just during the 2nd second (i.e., from time t= 1 s to t = 2 s)?
Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per
second. Answer B is wrong because velocity increases. Answer C is wrong because the
distance increases every second. Ans. E is wrong because the derivative of distance with
respect to time gives the velocity, not the acceleration.
Explanation:
can someone help me convert these?
Assuming you are supposed to write each conversion in scientific notation:
(2) 1 m = 100 cm, so
(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m
(3) 1 km = 1,000 m, so
(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m
(4) 1 m = 1,000 mm = 10³ mm, so
(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm
(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so
(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m
(6) 1 g = 1,000,000 µg = 10⁶ µg, so
(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g

convert 300 k into Celsius scale
Answer:
Given, kelvin temperature = 300 K
C = K – 273.15
C = 300 – 273.15
C = 26.85
Therefore, 300 Kelvin is equal to a celsius temperature of 26.85 °C

A scientist adds different amounts of salt to 5 bottles of water. She then
measures how long it takes for the water to boil. What is the responding
variable in this experiment?
O A. The time it takes for the water to boil
O B. The amount of salt added to the water
C. The kind of bottles used
D. The brand of salt used
Answer:
A. The time it takes for the water to boil
It is because salt was added into the water. So the responding variable is the time taken to boil the water.
hope this help u. good luck
A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?
Answer:
[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]
Explanation:
We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F= \ m \times a[/tex]
1. Calculate AccelerationThe mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).
[tex]v_f=[/tex]10 m/s [tex]v_i=[/tex]0 m/s t= 5 sSubstitute these values into the formula.
[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s[/tex]
[tex]a= 2 \ m/s^2[/tex]
2. Calculate ForceNow we know the mass and acceleration of the wheelbarrow
m= 20 kg a= 2 m/s²Substitute the values into the force formula.
[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]
[tex]F= 40 \ kg*m/s^2[/tex]
Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.
[tex]F= 40 \ N[/tex]
Answer:
40 N
Explanation:
We know that
F = ma
and
a = (v - u)/t
So,
F = m(v - u)/t
F = 20(10 - 0)/5
F = 20(10/5)
F = 20(2)
F = 40 N

Does a fan that is not spinning have energy?
Answer:
Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.
A stream of electrically charged particles flowing from the sun is called the
a. Van Allen belt.
b. magnetosphere.
c. solar wind.
d. magnetic field.
Answer:
solar wind
Explanation:
the sun's atmosphere is made of hydrogen which itself made subatomic particle. These particle are constantly boiling off the sun and streaming outward at very speed. So, the sun's magnetic field and particles are called solar wind.
Answer:
c
Explanation:
Solar wind
a 16 Watt bulb is used for 5 hrs. what is the energy consumed by the bulb
Energy = (power) x (time)
Energy = (16 watt) x (5 hours)
Energy = 80 watt-hours
or
Energy = 0.08 Kilowatt-hours
or
1 watt = 1 joule/second
5 hours = 18,000 seconds
Energy = (16 joule/sec) x (18,000 sec)
Energy = 288,000 Joules
Explanation:
A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.
(16×5 ) watt-hour=80Wh.
Convert it to kilowatt-hour i.e 0.08 KWh/day.
So 0.08 KWh is the energy consumption for one day.

Las dos líneas más largas del terreno de juego se denominarán líneas de banda. Las dos más cortas se llamarán líneas de meta. El terreno de juego será rectangular y la longitud de las líneas de banda deberá ser mayor que las de las líneas de meta. La longitud de la línea de banda debe tener como mínimo 90 metros y como máximo 120 metros. La anchura de la línea de meta debe de tener como mínimo 45 metros y como máximo de 90 metros. Todas las líneas del terreno de juego deberán se líneas continuas y tener la misma anchura, como máximo 12 cm., menos las líneas de meta que deben tener la misma anchura que los postes y larguero de la portería. Todas las líneas que delimitan al campo forma parte del terreno de juego. El terreno de juego puede ser de tierra, césped natural ó césped artificial de color verde según las normas del reglamento de la competición. El terreno de juego está dividido en dos partes iguales por una línea que unirá los puntos medios de las dos líneas de banda. El centro del campo estará marcado con un punto situado en la mitad de la línea media que divide las dos partes iguales del campo, tomando este punto como centro, haremos circulo de un radio de 9,15 metros. También se puede poner un banderín en cada extremo de la línea de media, a una distancia mínima de 1 m al exterior de la línea de banda.
