A 78−kg skier is sliding down a ski slope at a constant velocity. The slope makes an angle of 21° above the horizontal direction

Feliz [49]

Answer:

274N 0.41

Explanation:

As he is sliding down in a constant speed then the force that accelerates him (weight) and the force that slows his down (friction) are equal.

then

<em>friction=mass x gravity x sin(21)</em>

Fr=78kg x 9.8m/s2 x sin(21)=274N

<em>friction= coefficient of kinetic friction x normal force of from the slope</em>

Fr= u x 78kg x 9.8m/s2 x cos(21)=274N

Fr= u x 78kg x 9.8m/s2 x cos(21)=274Nu=274/677=0.41

More recent findings of children with exceptionally high IQs _

Alenkasestr [34]

Answer:

Explanation:

Researchers and educators differ in how they define gift-

edness. Traditionally, researchers have defined giftedness

as high general intelligence as measured by a high global

IQ score (Hollingwort

Exceptionally intelligent students (hereafter referred to

as gifted students) face a variety of problems in ordinary

classrooms. They often are ostracized as being different

and weird and are labeled as nerds and geeks (Silverman,

1993a, 1993b). In addition, they face the problem of

boredom due to lack of an appropriate level of challenge

(Csikszentmihalyi, Rathunde, & Whalen, 1993; Gross,

1993). Teachers often make little accommodation to the

needs of these children, and many teachers have little

or no special training in how to teach such exceptional

children

Gwen tells her college roommate Lindsey that she thinks clowns are disgusting and that she is repulsed by the idea of watching c

MA_775_DIABLO [31]

Answer:b) Reaction

Explanation:

Gwen is using Reaction Formation defense mechanism which got triggered when a person true feeling is not accepted by society or considered it illegal, so they convince others and themselves that the opposite is true.

They often exaggerate over the topic to prove their point. Though Gwen always wanted to be a clown but due the fact that her college roommate dislikes the clown so her reaction formation came into effect.

What does the 2 mean in the formula 5Mg3(PO4)2?

anastassius [24]

Answer: There is two (PO4) in the formula

Explanation:

Just be aware of the difference between numbers to the right and left: 5Mg3 means there are a total of 5 Mg (if 3 is a number in the bottom left) the 3 in (PO4) means there are 3 PO4 but because of the 2 it could mean there are 6.

Depends if the elements are separated

A pool is 31.4 m long and 40.0 m wide. if the average depth of water is 3.30 ft, what is the mass (in kg) of water in the pool?

olga nikolaevna [1]

The mass (in kg) of water in the pool is 1.264 $*$ $$$10^6$ kg.

A numerical measurement of inertia, a basic characteristic of all matter, in physics. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has.

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.

Given: A pool is 31.4 m long and 40.0 m wide. if the average depth of water is 3.30 ft

31.4 $*$ 40.0 = 1256 $$$m^2$
