Answer:
The family would not have hot water unless they were to heat the the water. They would have to depend on the stove in order to survive by heating the house to say alive and not freeze. They would also have to depend on the stove to get hot water to do any, but if the sun goes away for too long and everything starts to die then they will have to use what food and wood that they have in order to survive.

Answer:
ALMA is a trans-formative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. Most objects in the Universe emit this kind of energy, so the ability to detect it has been a driver for astronomers for decades.

Answer:
Explanation:
We shall represent speed in vector form
First speed
v₁ = 1.5 cos 14 i + 1.5 sin 14 j
= 1.455 i + 0.363 j
v₂ = 4.4 cos 33 i + 4.4 sin 33 j
= 3.69 i + 2.39 j
v₂ - v₁
3.69 i + 2.39 j - 1.455 i - 0.363 j
= 2.235 i + 2.027 j
acceleration
= v₂ - v₁ / time
= ( 2.235 i + 2.027 j ) / 23
= .097 i + .088 j
force = mass x acceleration
= 398 x ( .097 i + .088 j )
= 38.6 i + 35.02 j
Magnitude of force F
F² = 38.6² + 35.02²
F = 52.11 N
Tan θ = 35.02 / 38.6
θ = 42° north of east.
<span>Como sabemos a quantidade de tempo que leva a Fernando para chegar à escola, quando sua classe começa e termina, e quanto tempo leva para chegar em casa, podemos resolver quanto tempo Fernando estava longe de casa. O que fiz primeiro foi adicionar os 40 minutos que levou Fernando para chegar em casa às 11:30 e chegou às 12:10. Foi quando Fernando chegou em casa, então tudo o que precisamos fazer agora é fator em 6:30 e descubra quanto tempo ele estava fora da casa. Eu fiz isso contando as horas e subtraindo os minutos extras. O tempo que Fernando acabou é de 5 horas e 40 minutos.</span>
Answer:
F = - 6.95 10⁻² j^ N
Explanation:
The force on a wire carrying current through a magnetic field is
F = i L x B
The bold letters indicate vectors, as the wire is in the positive Z axis and the magnetic field in the negative x axis, the force must be in the negative y axis
the force module
F = i LB
that there is 90º between the two vectors and the sin 90 = 1
let's calculate
F = 4.9 3.3 10⁻² 0.43
F = 6.95 10⁻² N
the force vector is
F = - 6.95 10⁻² j^ N
