Answer:
Wavelength of electromagnetic wave will be 5.281 m
Explanation:
We have given frequency of electromagnetic wave is 
Velocity of electromagnetic wave is 
We have to fond the wavelength of the electromagnetic wave
We know that velocity of electromagnetic eave is given by 
, here 
is wavelength and f is frequency
So 
Wavelength of electromagnetic wave will be 5.281 m
Answer:
1. True 2.0
Explanation:
1. When balanced forces are acting on an object, they have a constant velocity, meaning that the velocity remains the same.
2. When an object begins at a starting point and returns back to that same starting point, its displacement would be 0.
I'm pretty confident in these answers, however, you must have studied this more than me, so let me know if you have any questions or concerns at all, I'll be glad to help. :)
Answer:
77000 J
Explanation:
Formula for the heat energy is;
Q = m•c•Δt
We are given;
mass; m = 2 kg
Change in temperature; Δt = 110 - 10 = 100 °C
From online values, specific heat capacity of copper is; c = 385 J/kg.°C
Thus;
Q = 2 × 100 × 385
Q = 77000 J
Answer: The gravitational acceleration on planet X is 5 N/kg
On Earth (with the gravitational accelartion g_E) the mass of 2kg will correspond to
On planet X we are told the same measure is only 10N. Since there is a proportional relationship between g and F, we can calculate g_X:
Answer:
A) 6N
Explanation:
the weight of the astronaut on earth can be calculated with the formula
Weight = mass * gravity of earth
Since the gravitational force is one-hundredth of Earth, the formula should be
Weight = mass * (gravity of earth / 100)
Weight = (mass * gravity of earth) / 100
Since you already know the weight, you only need to divide by 100
Weight = (mass * gravity of earth) / 100
Weight = 600N / 100
Weight = 6N
