Answer:
A) True, B) False, C) False and D) false
Explanation:
Let's solve the problem using the law of conservation of energy to know if the statements are true or false
Let's look for mechanical energy
Initial
Emo = Ke = ½ k Dx2
Final
Em1= ½ m v12
Emo = Em1
½ k Δx2 = ½ m v₁²
v₁² = k / m Δx²
v₁ = √ k/m Δx
Now let's calculate the speed when it falls
Vfy² = Voy² - 2gy
Vfy² = - 2gy
Vf² = v₁² + vfy²
A) True v₁ = A Δx
.B) False. As there is no rubbing the mechanical energy conserves
.C) False the velocity is proportional to the square root of the height
v2y = v2 √2
. D) false promotional compression speed
Answer: 5.9cm
Explanation:
15N/3cm=5
Convert 3kg to N (29.42N)
Use the 5 from earlier to divide 29.42/5=5.884
Round to 5.9
5.9cm is the answer
(I don’t know if I solved this the correct way but I got it right. 5.9 is the correct answer)
Answer:you use / this
Explanation: for exmp 1/4 x 1/9=
Both are temples designed to inspire reflection, meditative thought and are places of significant art and design. The Ryoanji garden uses asymmetry, spacial composition, minimalism and little color that arranges three small islands in a perfectly kept graveled garden with a prominent cherry blossom; the stained glass window at Chartres Cathedral, however, uses light, complicated symmetrical patterns, figuration, lots of color on the two-dimensional form of the glass.
