Answer:
Magnitude of Vector = 79.3
Explanation:
When a vector is resolved into its rectangular components, it forms two vector components. These components are named as x-component and y-component, they are calculated by the following formulae:
x-component of vector = (Magnitude of Vector)(Cos θ)
y-component of vector = (Magnitude of Vector)(Sin θ)
where,
θ = angle of the vector with x-axis = 27°
Therefore, using the values in the equation of y-component, we get:
36 = (Magnitude of Vector)(Sin 27°)
Magnitude of Vector = 36/Sin 27°
<u>Magnitude of Vector = 79.3</u>
Answer:
When Earth passes directly between the sun and the moon, a lunar eclipse takes place. During a solar eclipse, the moon casts two shadows. One is called the umbra; the other is called the penumbra. An eclipse takes place when Earth or the moon passes through a shadow.

Explanation:
In short,the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time,roughly 13.8 billion years ago.At this time,all matter was compacted into a very small ball with infinite density and intense heat called a Singularity.

Respuesta:
4.9 × 10³ J
Explicación:
Paso 1: Información provista
- Masa del coyote (m): 30 kg
- Velocidad del coyote (v): 65 km/h
Paso 2: Convertir la velocidad del coyote de km/h a m/s
Vamos a usar los siguientes factores de conversion:
65 km/h × (1000 m/1 km) × (1 h/3600 s) = 18 m/s
Paso 3: Calcular la energía cinética del coyote (K)
Usarémos la siguiente fórmula.
K = 1/2 × m × v²
K = 1/2 × 30 kg × (18 m/s)² = 4.9 × 10³ J
