Answer:
Energy emitted by photon = 45.06 × 10−32 J
Explanation:
Energy of photon is given by E = hf
where
h is the Planck's constant whose value is 6.626×10−34J⋅s
f is the frequency of photon
________________________________________
given that
f = 6.8 x 104 Hz
1 HZ = 1 s^-1
E = 6.626×10−34J⋅s * 6.8 x 10^4 Hz
E = 45.06 × 10−32 J
Thus,
Energy emitted by photon is 45.06 × 10−32 J
Explanation:
In order to justify Marian's statement we have to look at the '' Amount per serving calories'' ⇒
In food label A we can see that this value is 160 calories
In food label B we can see that this value is 50 calories
⇒ 160 calories is slightly more than three times 50 calories
Otherwise If we want to justify Johan statement we need to look at the '' serving size '' ⇒
In food label A we can see that the serving size is 1 cup (237 mL)
In food label B we can see that the serving size is
cup (56g)
Working with the information of the food label A we can write the following expression :
⇒ Looking at the value of ''
'' ⇒


If we look at the same amount of portion volume :
In
cup of food A we have 40 calories
In
cup of food B we have 50 calories
We could conclude that Food B has more calories.
That's how both claims could both be justified.
Answer:If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2.
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
Explanation:
D. Biased data is likely skewed for or against some variable tested, meaning it isn't an honest study.
Answer:
Explanation:
percentage error = error x 100 / correct value
= (2.73 - 2.70) x100 / 2.70
= 1.11 %
The element is Aluminium whose density is 2.702 grams / cc
Boiling point of Aluminium = 2519⁰C .
