Explanation:

G - given - current (I) and resistance (R)

R - requirement - Voltage (V)

A - analysis - solve V=IR

S - statement - ??

S - solution - V= 500x50 = 25000volts

The Sears Tower in Chicago is approximately 444 m tall Suppose a book
Reptile [31]

Answer:

A. 66.0 m/s downwards

Explanation:

The Tower has a height of 444m

The book is dropped ,finding the velocity of the book 222m above the ground, means the book will be on air for a  height of 222 m .

Apply the formula for free fall in a horizontal projection as;

h= u²×sin²∅ /2g  where

h= maximum height =222m

g= acceleration due to gravity =9.81 m/s²

∅ = projectile angle = 0

u = velocity of the book

Applying the formula as ;

h= u²×sin²∅ /2g

222 = u²/2*9.81

222*19.62 = u²

4355.64 = u²

√4355.64 = u

65.99 m/s = u

66 m/s  downwards

A 52–newton bird feeder is tied to a cord, which is attached to a tree branch. Describe the tension force of the rope.
ziro4ka [17]
Hi, thank you for posting your question here at Brainly.

When the object is at equilibrium and the object is just freely hanging from the cord, then the summation of forces along the y direction would just be the tension of the cord and the weight of the object. Since both forces are opposite in direction, at equilibrium, they are equal. Hence, in this case, the tension is also equal to 52 N.

A ball bounced by a basketball player on the floor bounces back up at her. Newton's First Law Newton's Second Law Newton's Third
taurus [48]

Answer:

Newton's Third Law of Motion

Explanation:

Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.

This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.

In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.

According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.

Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.

What does bacteria have in it?
salantis [7]

Answer:

Structure. Bacteria (singular: bacterium) are classified as prokaryotes, which are single-celled organisms with a simple internal structure that lacks a nucleus, and contains DNA that either floats freely in a twisted, thread-like mass called the nucleoid, or in separate, circular pieces called plasmids
