Answer:
32 °C.
Explanation:
Hola.
En este caso, debemos entender que la relación entre el calor y la temperatura viene dada por:
De este modo, dado que estamos estudiando la misma sustancia (agua) con masa constante, la relación calor-temperatura es lineal y directamente proporcional, por tal razón, si se duplica el calor suministrado, la temperatura también será duplicada, de modo que:
¡Saludos!
Answer:
Angle between incident ray and reflected ray will be 104°
Explanation:
We have given angle of incidence = 52 °
From law of reflection angle of incidence will be equal to angle of reflection
So angle of reflection will be also 52°
We have to find the angle between incident ray and reflected ray
As the incidence angle and reflected angle both is from normal of the surface and opposite to each other
So angle between incident ray and reflected ray will be 52°+52° = 104°
Based on the information you provided, this means the wave is traveling 50 meters every ten seconds. Meaning it is traveling 50/10 meters per second.
When you simplify you get 5 meters per second.
Answer:
Explanation:
The electric field outside the sphere is given as,
E = k Q /r²
here Q = n x 1.6 x 10⁻¹⁹ C
where n is the number of electons
if the dimeter of sphere d= 25 cm= 0.25 m
then the radius r = 0.125 m
we get
n= E r²/ k x 1.6 x 10⁻¹⁹ C
n = 1350N/C x (0.125m)² / (8.99 x 10⁹ N m²/C² x 1.6 x 10⁻¹⁹ C)
n = 14664731646
The acceleration of the first block (4 kg) is -9.8 m/s².
The given parameters:
- <em>Mass of the first block, m₁ = 4.0 kg</em>
- <em>Mass of the second block, m₂ = 2.0 kg</em>
The net force on the system of the two blocks is calculated as follows;
where;
- <em>T </em><em>is the tension in the connecting string due weight of the first block</em>
Thus, the acceleration of the first block (4 kg) is -9.8 m/s².
