Answer:
Child maltreatment encompasses various forms of abuse, including sexual, physical, and psychological harm inflicted upon minors.
There are five distinct psychological viewpoints regarding childhood maltreatment:
- One major contributor to childhood maltreatment is poverty, which adversely affects children's mental well-being.
- Parents may fail to provide adequate care for their children.
- Children are often emotionally fragile, and any negative thoughts can lead to depression.
- Inadequate communication can sometimes foster a sense of inferiority in children.
- Social discrimination based on race and gender may disrupt a child's psychological stability.
The full question reads;
Jason is employed at a moving company. A wooden crate weighing 75 kg is positioned on the wooden ramp of his truck, inclined at an angle of 11°.
What is the force magnitude, directed parallel to the ramp, that he needs to apply to initiate the upward movement of the crate?
Answer:
F = 501.5 N
Explanation:
We have the following information;
Mass of the wooden crate; m = 75 kg
Incline angle; θ = 11°
To move the wooden crate up, we must consider that friction is acting in the opposite direction of the movement along the inclined surface. Therefore, the force required can be expressed by;
F = mgsin θ + μmg cos θ
Using online resources, the coefficient of friction between wooden surfaces is μ = 0.5
Thus;
F = (75 × 9.81 × sin 11) + (0.5 × 75 × 9.81 × cos 11)
F = 501.5 N
The mass of the baked loaf will be lower than that of the dough.
Answer
Data provided:
mass of the block = 200 g = 0.2 Kg
Velocity at A = 0 m/s
Velocity at B = 8 m/s
distance of slide = 10 m
height of the block = 4 m
calculation for the block's potential energy
P = m g h
P = 0.2 x 9.8 x 4
P = 7.84 J
kinetic energy calculated as
Work done = P - KE
work = 7.84 - 6.14
work = 1.7 J
b) using the formula v² = u² + 2 a s
0 = 8² - 2 x a x 10
a = 3.2 m/s²
ma - μ mg = 0
