The new speed of the aircraft is equal to 774.61 mph north of east.
Why?
To calculate the new speed, we first need to know the horizontal component of the wind's speed (moving to the east) since the jet is moving to the east.
We can use the following formulas to solve the problem:
We are given the following information:
So, substituting and calculating we have:
For the vertical speed, we have:
Now, to calculate the airplane speed , we can use the following equation (Pytagorean Theorem):
Hence, we have that the new speed is equal to 774.61 mph north of east.

Answer:
Q = 836.4 Joules.
Explanation:
Given the following data;
Mass = 100 grams
Initial temperature = 25°C
Final temperature = 45°C
We know that the specific heat capacity of water is equal to 4.182 J/g°C.
To find the quantity of heat;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 45 - 25
dt = 20°C
Substituting the values into the equation, we have;
Q = 836.4 Joules.
10 – 3 + 8 = 15 meters
10 + 3 + 8 = 21 meters
Her total traveled is 21 meters, displacement is 15 meters.
Answer:2.7m/s^2
Explanation:
mass=2.3kg
Force=6.2Newton
Acceleration=force ➗ mass
Acceleration=6.2 ➗ 2.3
Acceleration=2.7m/s^2
Sunspot. Sunspots are temporary cooler areas on the Sun's surface caused by changes in its magnetic field.
