Explanation:
here, force applied (N) = 345 N
or, mass of scooter (m) = 70 kg
now, acceleration (a) = ?
we know, force = mass × acceleration
or, 345 = 70 × acceleration
or, acceleration = 345/70
therefore, acceleration = 4.9 m/s2 (meter/second square)
Answer:
D. Because they are using space technology on a shirt so people can wear it on earth as well
In two significant figure 360K
The temperature difference (ΔT) can be calculated as the boiling temperature minus the freezing temperature in Fahrenheit.
Hence,
ΔT = 212 - 32
ΔT = 180°F
To convert to °F to kelvin, we use the formula below
= (°F - 32) × 5/9 + 273.15
= (180°F - 32) × 5/9 + 273.15
= 355.37K ⇔ 360K
The correct option is H
From the question we are told that
The index of refraction of coating is
The index of refraction of material is
Generally the condition for constructive for a thin film interference is mathematically represented
Here t represents the thickness
For minimum thickness m = 0
So
=>
