Answer:
C. The provider's success claims seem too good to be true.
B. Reflection gratings on plastic
C. Transmission gratings on glass
D. Replica transmission gratings on plastic
Holographic gratings are likely to produce the brightest spectra.
The correct answer is A. Holographic gratings are likely to produce the brightest spectra. Holographic gratings are created using interference patterns produced by laser light, resulting in highly precise and bright spectra. Reflection gratings on plastic (option B), transmission gratings on glass (option C), and replica transmission gratings on plastic (option D) can also produce spectra, but holographic gratings are known to have superior brightness and quality.

Which object has the greatest acceleration?
34
Ow
OZ
Answer:
Y
Explanation:
The answer is y because,
W: (29-11)/6 = 3
X: (34-10)/12 =2
Y: (40-12)/7=4
Z= (28-20)/8=1
4 is greater then all, therefore the answer is Y
Answer:
X
Explanation:
v=u+at but t is constant so
a=v-u
for x
a=29-10
a=19
which marks the greater acceleration
Answer:
a) 0.5s
b) 2.45m/s
Explanation:
The toy car in figure 6-12 runs off the edge of a table that is 1.225m high. The car lands 0.400m from the base of a table.
a) How long did it take the car to fall?
b) How fast was the car going on the table?
don't now if this helps but let me now if it did
The question is about a physics concept called projectile motion. First, we calculate the time the toy car is in the air using the height of the table and gravity, and then we find the horizontal velocity of the car as it leaves the table.
The question is about a situation where a toy car runs off the edge of a table and lands on the floor. This situation is a classic problem in physics pertaining to projectile motion or the motion of an object thrown in the atmosphere. Here, the motion is two-dimensional, including both vertical (free fall) and horizontal (uniform) motion.
First, calculate how much time the car is in the air using the height of the table and the acceleration due to gravity (approx. 9.81 m/s²). Using the free fall equation, t = √(2h/g), where h is the height of the table and g is the gravity, we get t = √(2*1.225m/9.81 m/s²) = 0.5 seconds. This is the time it takes for the car to hit the floor.
Next, we find the horizontal velocity using the formula s = d/t, where s is speed, d is distance and t is time. So, s = 0.400m/0.5s = 0.8 m/s. This is the speed of the car as it leaves the table.
