Answer:
object 1 had faster-moving particles.
Right before it breaks of, because all the other options are examples of Kinetic energy while the A. answer is the only one describing potential energy.
Answer: THIS IS THE EXACT ANSWER
Three effective techniques Ann could use to learn all the US states and their state capitals are visualization and association, creating a mnemonic device, and rhyming. She could learn some of the states and their capitals by visualizing her own experiences in or about the state. As an example of association, if Ann visited Idaho last winter to see her twin brothers, she might think “I went to Idaho to visit the boys” (sounds like Boise). By employing association, she connects her own life experience to the information she wants to remember to make recalling the information easier. To remember the capital of Washington, Ann might create a mnemonic device like “George Washington went to the Olympics” (Washington’s capital is Olympia). Mnemonic devices organize information to encode it in a way that helps with recall. To effectively use rhyming, she might remember Michigan is a northern state and use “Reindeer prancing in Lansing.” Rhyming provides a cue that helps with recall. All three of these techniques work in the encoding and retrieval stages.

0.061 J
Explanation:
The kinetic energy of an object is given by
where
m is the mass of the object
v is its speed
For the toy truck in the problem, we have
m = 0.1 kg is its mass
v = 1.1 m/s is its speed
Putting the numbers into the equation, we find
Answer
given,
B = 6.40 mm , L = 26 cm , τ = 3.90 × 10⁻² s
general wave equation
y = A cos (k x - ωt)
where A is the amplitude of the
a) Amplitude of the given wave
B = 6.40 mm
b) Wavelength of the given wave
λ = L
λ = 26 cm
c) wave frequency
f = 25.64 Hz
d) speed of wave will be equal to
v = f λ
v = 25.64 x 0.26
v = 6.67 m/s
e) direction of propagation will be along +ve x direction because sign of k x and ωt is same as general equation.
