Answer:
Explanation:
Given
First bicycle travels 6.10 km due to east in 0.21 h
Suppose its position vector is
After that it travels 11.30 km at east of north in 0.560 h
suppose its position vector is
after that he finally travel 6.10 km due to east in 0.21 h
suppose its position vector is
so position of final position is given by
t=0.21+0.56+0.21=0.98 h
For direction
w.r.t to x axis
Answer:
no. the moon has less of a gravitational pull. therefore it would weigh less than 40n.
Explanation:
Answer:
W = 9.604 J
Explanation:
Given data:
Function of force with respect to displacement (x) as:
F = F₀(x/x₀ - 1)
F₀ = 0.98 N
x₀ = 4.9 m
on substituting the values in the given function, we get
F = 0.98 × [(x/4.9) - 1]
Now, the work done is given as:
W = F . dx
substituting the value of force, we have
W = 0.98 × [(x/4.9) - 1] . dx
on integerating the above formula for the limit x = 0 to x = 2x₀ = 2 × 4.9 = 9.8 m
we get
W =
or
W =
or
W = 0.98 × [(9.8²/4.9 - 9.8) - 0]
or
W = 9.604 J
I think the correct answer is a d ike. As magma rises, it carves a tube-shaped structure called a d ike. In geology, it is an igneous rock that is formed and cuts across a rock and a result of magma intrusion and cooling of the magma. It is usually in a tube shaped.
When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls
