Answer:

N = 2490 N

Explanation:

Determine the upward force exerted by the horizontal platform on the box as it is lowered.

It is given that,

Mass of a box, m = 300 kg

Starting from rest at time t = 0 seconds, the box is lowered with a downward acceleration of 1.5 m/s².

It is assumed to find the upward force exerted by the horizontal platform on the box. It is given by :

mg-N=ma

N=m(g-a)\\\\N=300\left(9.8-1.5\right)\\\\N=2490\ N

So, the normal force is 2490 N.

Answer:

Bullying in the schools has negative effects on individual students and on the school climate as a whole. Bullying can cause long-term problems for both the victims of bullying and the bullies themselves. To explore the effects of bullying on adolescents, we will define bullying, identify the characteristics of bullies and victims, outline the extent and consequences of bullying, and present resources for further information and assistance.

Bullying is any behavior that is initiated by one or more students against a victim or victims that causes physical or psychological intimidation. Bullying behaviors can be classified as either direct (such as teasing, threatening, hitting, or stealing) or indirect (such as rumor spreading or social isolation). Boys typically employed direct methods of bullying, while girls tend to use in direct methods. Either way, behaviors must occur repeatedly overtime to be classified as bullying.

Characteristics of Bullies and Victims

There are specific behaviors that bullies tend to exhibit. The bullies often need to feel powerful and in control. They may feel no remorse when they inflict injury and suffering on others. Bullies tend to defy authority and are likely to break school rules. They seem to have little anxiety and appear to possess high self-esteem. Students who come from homes characterized by physical punishment tend to be more likely to exhibit these types of behaviors.

Victims also tend to exhibit specific characteristics. They are often anxious, insecure, cautious, and have low self-esteem. Victims tend to be socially isolated, and may lack social skills and friends. Because they tend to be weaker than their peers, either physically or socially, victims rarely retaliate against bullies. Students who have close ties with their parents/guardians or who have overprotective parents/guardians are more likely to be victimized by bullies.

Tom [10]

Answer:

v_f = 82.3 m/s

Explanation:

When a suspended string makes and angle of 25 degree while aircraft is accelerating on runway then we can use force equations to find the acceleration of the aircraft

So we will have

T sin\theta = ma

T cos\theta = mg

now from above two equations we have

a = g tan\theta

a = (9.81) tan25

a = 4.57 m/s^2

now if it took 18 s to take off we can have final speed of the aircraft given by

v_f - v_i = at

v_f - 0 = (4.57)(18)

v_f = 82.3 m/s

When a spinning star shrinks in radius, it speeds up. Which of the following statements explains this phenomenon?
Sever21 [200]

Answer:

B.)Angular momentum is always conserved

Explanation:

Angular momentum is given by:

L=mvr

where

m is the mass of the object

v is its speed

r is the distance between the object and the centre of its circular trajectory

In absence of external torques, angular momentum is always conserved. That means that for the spinning star, if its radius r decreases (because it shrinks), in order for L (the angular momentum) to be conserved, the speed (v) must increases, therefore the spinning star speeds up.

So, the correct choice is

B.)Angular momentum is always conserved
