mass₃<mass₁=mass₅<mass₂=mass₄
Explanation:
Data points:-
1. mass: m speed: v
2. mass: 4 m speed: v
3. mass: 2 m speed: ¼ v
4. mass: 4 m speed: v
5. mass: 4 m speed: ½ v
We know that the formula for Kinetic energy (KE) is ½ mv²
Where m represents the mass of the object
v represents the object's velocity
<psubstituting the="" given="" values="" for="" mass="" and="" speed="" from="" previous="" data:="">
The KE of Body 1(mass₁) = ½*m*v² = mv²/2
KE of Body 2(mass₂) = ½*4m*v² = 2mv²
KE of Body 3(mass₃) = ½*2m*(1/4v)² = mv²/16
KE of Body 4(mass₄) = ½*4m*v ² = 2mv
²
KE of Body 5(mass₅) = ½*4m*(1/2v)² = mv²/2

Answer:
Explanation:
To begin with, we must determine the pressure acting on the sphere, which is calculated using:
where
denotes the atmospheric pressure
represents the density of the water
signifies the acceleration due to gravity
indicates the depth
By substituting these values,
The sphere's radius is calculated as r = d/2 = 1.1 m/2 = 0.55 m
Thus, the sphere's total surface area can be expressed as
Consequently, the inward force acting on the sphere equals
Answer:
The temperature of the cooler object was nearly at room temperature. As a result, the system underwent minimal change
Explanation:
In a closed system with two objects at varying temperatures, heat energy typically flows from the hotter object to the cooler one. This transfer is more pronounced when there is a significant temperature disparity between the objects. Conversely, if the temperature difference is minor or negligible, the resulting change will be minimal.
Respuesta:
La magnitud de la aceleración resultante es 2.2 
Explicación:
La masa (m) del velero es 2000 kg
La fuerza que actúa sobre el velero debido a la marea del océano es 
= 3000N
Hacia el este significa que se da a lo largo de la dirección positiva del eje x
Entonces
= 3000N y 
= 0
La fuerza del viento que actúa sobre el velero es
6000N dirigida hacia el noroeste, lo que significa a un ángulo de 45 grados sobre el eje negativo x
Luego
= -(6000N) cos 45 grados = -4242.6 N
= (6000N) cos 45 grados = 4242.6 N
Por lo tanto, la fuerza neta que actúa sobre el velero en la dirección x es
= - 3000 N + 4242.6 N
= - 3000 N +4242.6 N
= 1242.6N
La fuerza neta que actúa sobre el velero en la dirección y es
= 0+ 4242.6N
= 4242.6N
La magnitud de la fuerza resultante =
Usando el teorema de Pitágoras de 1243 N y 4243 N
4420.8 N
