Answer:
6.25 mph
Explanation:
You would divide 25 by 4 to get the average miles per hour.
Answer:
1.2×10⁶ Hz
Explanation:
Applying,
v = λf............. Equation 1
Where v = speed of wave, λ = wavelength, f = frequency.
make f the subject of the equation
f = v/λ............... Equation 2
From the question,
Given: v = 3.0×10⁸ m/s, λ = 2.5×10² m
Substitute these values into equation 2
f = 3.0×10⁸/2.5×10²
f = 1.2×10⁶ Hz
Answer:
1, 4, 5, see the explanation below
Explanation:
We must remember that scalar magnitudes are distinguished by having only a physical quantity, that is, they have no sense or direction as an example of scalar quantities, we find mass, temperature, energy, specific heat, power among others.
1 . 150 [grams] , because is a mass = scalar
4. 5 kilometer [race], is an amount = scalar
5. 34 steps, is an amount = scalar
Number 2, and 3 are vectors because they have amount and direction.
Answer:
The nature of the environment and the animal's interaction with it determines much of the character of the brain.
Explanation:
In fact, most of what we would use to describe ourselves to others reflects this sort of information storage. Much of this information is unique to the individual and hence may involve different mechanisms from those used for species-typical information storage.
The average speed of the ball is 0.15 m/s.
The average speed of the ball can be calculated using the formula below.
<h3 /><h3> Average speed: </h3>
This is the ratio of the total distance to the total time traveled by a body
<h3 /><h3>Formula:</h3>
- S = d/t.................. Equation 1
<h3>Where:</h3>
- S = Average speed
- d = total distance
- t = total time.
From the question,
<h3>Given:</h3>
Substitute these values into equation 1
Hence, the average speed of the ball is 0.15 m/s.
