m = mass of the truck traveling = 2500 kg
v = speed of the truck traveling = 75 km/h = 75 (km/h) (1000 m/ 1 km) (1 h /3600 sec) = 20.83 m/s
h = plank's constant = 6.63 x 10⁻³⁴
λ = wavelength of truck = ?
according to de broglie's principle, wavelength of truck is given as
λ = h/(mv)
inserting the values in the above equation
λ = (6.63 x 10⁻³⁴)/((2500) (20.83))
λ = 1.3 x 10⁻³⁸ m
It is one of the most common types of chemical reactions and can also be called a synthesis reaction. In this reaction, two or more chemical species combine to form a more complex product.
Answer:
6750 J
Explanation:
The specific heat capacity of iron is 450 J/kg/K
Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.
Therefore;
m = 3 kg, c = 450 J/kg/K and θ = 5°C
Quantity of heat = 3 × 450 × 5
<u>= 6150 Joules</u>
.2x350mg = 70mg which converts to .070g.
.35g/.070g = 5 tablets.
