Answer:
La transformación energética, transformación de la energía, conversión energética o conversión de la energía es el proceso de cambiar la energía de un tipo de energía a otro. En física, la energía es una cantidad que proporciona la capacidad de realizar un trabajo (por ejemplo, levantar un objeto) o proporciona calor. Además de ser convertible, de acuerdo con la ley de conservación de la energía, la energía es transferible a una ubicación u objeto diferente, pero no se puede crear ni destruir.
La energía en muchas de sus formas se puede utilizar en procesos naturales o para proporcionar algún servicio a la sociedad, como calefacción, refrigeración, iluminación o realizar trabajos mecánicos para operar máquinas. Por ejemplo, para calentar una casa, el horno quema combustible, cuya energía potencial química se convierte en energía térmica, que luego se transfiere al aire de la casa para elevar su temperatura.
Explanation:
The speed of the two boats are 7 miles per hour and 24 miles per hour.
Explanation:
Let the speed of the first boat be x miles per hour and second boat be x+17 miles per hour.
As they move at right angle to each other, this problem can be solved using Pythagoras theorem.
The two boats will form a right angle with hypotenuse 25 miles after one hour.
Applying the theorem we get,
∴ x= -24 and 7
As speed cannot be negative,
We get speed of first boat = 7 miles per hour and
Speed of second boat = 7+17 = 24 miles per hour.
Displacement is a vector quantity. So, you incorporate the vector calculations when you try to determine the resultant vector. This is the shortest path from the starting point to the endpoint. If they are moving on one axis only, you use sign conventions. For motions moving to the left, use the negative sign. If it's moving to the right, then use the positive sign. Now, it the object moves 2 km to the left, and 2 km also to the right, the displacement is zero.
Displacement = 2 km - 2km = 0
Generally, the equation is:
<span>Displacement = Distance of motion to the right - Distance of motion to the left</span>
Answer:
772.65 years.
Explanation:
Semi major axis = R = 84 AU = 1.257 × 10¹³ m
According to the 3rd law of Kepler, T² = 4 π² R³ / GM
Here R is the semi major axis. G = 6.67 × 10⁻¹¹ SI units.
M is the mass of the Sun = 1.98 x 10³⁰ kg
T² = 4 (3.14)³ (1.257 × 10¹³ )³÷ (6.67 × 10⁻¹¹)(1.98 x 10³⁰)
⇒ Time period = T = 2.44 x 10¹⁰ seconds
1 s = 3.17 × 10⁻⁸ years
Converting the seconds to years, T = 772.65 years.
Answer:
1.47 J/kg
120 m
Explanation:
The maximum height it can jump in a single leap 15 cm, = 0.15 m
to get the kinetic energy per kg of mass, we need to find the takeoff speed. The take off speed can be calculated by using the formula
v =
where h = 0.15
v =
v =
v = 1.715 m/s
energy per kg of mass =
1/2 * (1.715) = 1.47 J/Kg
TJe height a human can jump when compared to the flea is
2 m/2.5 mm * 15 cm =
2/0.0025 *0.15 =
800 * 0.15 = 120 m
