Answer:
31.68 meters per second.
Explanation:
Speed is equals to Distance divided by Time, so, this means that speed is inversely proportional to time and directly proportional to distance.
Here, Distance is given which is 274 meters.
Time taken to cover the given distance is 8.65 seconds.
So, by putting the values of distance and time in the formula of speed we will get the top speed of Cheetah which is 31.68 meters per second.
Answer:
-2 m/s
Explanation:
The computation of the acceleration of the block is as follows:
The volume of the block is
V = 1kg ÷ 1,000 kg/m^3 = 1 ÷ 1,000 m^3
Now at the time of submerging in the oil
Net force is
= -2 m/s
Answer:
19.5°
Explanation:
The energy of the mass must be conserved. The energy is given by:
1) 
where m is the mass, v is the velocity and h is the hight of the mass.
Let the height at the lowest point of the be h=0, the energy of the mass will be:
2) 
The energy when the mass comes to a stop will be:
3) 
Setting equations 2 and 3 equal and solving for height h will give:
4) 
The angle ∅ of the string with the vertical with the mass at the highest point will be given by:
5) 
where l is the lenght of the string.
Combining equations 4 and 5 and solving for ∅:
6) 
Momentum before the hit:
p = mv = 0.01 * 300 + 1 * 0
Momentum after the hit:
p = 0.01 * 150 + 1 * v
Momentum is conserved:
0.01 * 300 = 0.01 * 150 + v
3 = 1.5 + v
v = 1.5
The velocity of the block after the collision is 1.5 m/s.
Correct answer choice for question 1 is:
A) Figurative language
Explanation:
Figurative language uses terms of speech to be more powerful, effective, and impactful. Characters of speech such as metaphors, similes, and implications go away the usual meanings of the words to give users new acumens. On the other hand, alliterations, imageries, or echoes are symbolic tools that review the minds of the users. Figurative language can perform in various forms with the use of various literary and eloquent articles.
Correct answer choice for question 2 is :
D) Words that trigger the imagination to remember by appealing to the five senses
Explanation:
Imagery, in a literary text, is an author's use of rich and detailed language to add intensity to their work. It advances to human senses to increase the reader's knowledge of the work. Powerful kinds of comparison join all of the senses. There are seven main kinds of imagery, each resembling a sense, feeling, action, or reaction. Olfactory imagery concerns, scents, or the sense of smell. Gustatory imagery concerns tastes or the sense of taste. Tactile imagery concerns physical forms or the feeling of touch.
