Answer:
<h2>735 m</h2>
Explanation:
The distance covered by an object given it's speed and time taken can be found by using the formula
distance = speed × time
From the question we have
distance = 7.5 × 98 = 735 m
We have the final answer as
<h3>735 m </h3>
Hope this helps you
Since Power is equal to the product of Force and Displacement all over time, George needs 6.86 W of power to push the wheelbarrow. Power can also be calculated by multiplying Force applied on the object and the speed of the object being applied of the force.
Answer:
a) t= 0.515 s
b) vf= 5.047 m/s
Explanation:
Because ball move with uniformly accelerated movement we apply the following formulas:
d= v₀t+ (1/2)*g*t² Formula (1)
vf= v₀+gt Formula (2)
Where:
d:displacement in meters (m)
t : time in seconds (s)
v₀: initial speed in m/s
vf: final speed in m/s
g: acceleration due to gravity in m/s²
Known data
v₀=0
d= 1.30 m
g= 9.8 m/s²
Problem development
a)
We appy the formula 1 to calculate the time (t):
d= v₀t+ (1/2)*g*t²
1.30= 0+ (1/2)* (9.8)*t²
1.30=4.9*t²
t²=1.30/4.9
t= 0.515 s
b) We appy the formula 2 to calculate the final speed (vf):
vf= v₀+gt
vf= 0+(9.8)*(0.515)
vf= 5.047 m/s

<h2>
<em><u>A) Different parts of the moon throughout the month</u></em></h2>
Explanation:
Every thing I researched on the moon never says you can see all sides of the moon while its spinning expect the full moon. Your gonna see different sides of the moon because it is spinning not staying still. The last one is wrong because the moon goes threw a cycle. (sorry if anything is wrong this is just what I've been learning and understanding about the moon)
Answer:
d)energy
Explanation:
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
