Answer:
2621.25 meters
Explanation:
First, write down what we are given.
Initial velocity = 27.5 m/s
Final velocity = 42.4 m/s
Time = 75 seconds
We need to look at the kinematic equations and determine which one will be best. In this case, we need an equation with distance. I am going to use , but you can also use the other equation,
We need to find acceleration. To find it, we need to use the formula for acceleration: . Plugging in values,
Next, plug in what we know into the kinematics equation and solve for distance.
Answer:
The magnitude of the resultant vector R is 50 meters ⇒ 2nd answer
Explanation:
<u><em>The resultant vector</em></u> is the vector sum of two or more vectors
If the two vectors perpendicular to each other, then the magnitude of
the resultant vector is the square root of the sum of their squares
If x and y are two vectors perpendicular to each other, then the
magnitude of its resultant vector R is:
→
Lets solve the problem
A right triangle with the base labeled 40 meters and the height labeled
30 meters
The hypotenuse is a dotted arrow labeled R
→ The base and the height of the right triangle are perpendicular
→ The hypotenuse is the resultant vector of them
Assume that x represents the base of the triangle and y represents the
height of it
By using the rule above
→ x = 40 m , y = 30 m
→
→
→
→
<em>The magnitude of the resultant vector R is 50 meters</em>
Answer:
The value is
Explanation:
From the question we are told that
The amount of power delivered is
The time taken is
The wavelength is
Generally the energy delivered is mathematically represented as
Where is the Planck's constant with value
c is the speed of light with value
So
=>
Answer:
r = 4.62 cm
Explanation:
Mass of a coffee, m = 370 g
Height of the mug, h = 5.5 cm
We need to find the inside radius of the mug. Density of an object is equal to the mass per unit volume. It can be given by :
So, the inside radius is 4.62 cm.
