Answer:
7.7 km 26°
Explanation:
The total x component is:
x = 2.5 cos(35°) + 5.2 cos(22°) = 6.87
The total y component is:
y = 2.5 sin(35°) + 5.2 sin(22°) = 3.38
The magnitude is:
d = √(x² + y²)
d = 7.7 km
The direction is:
θ = atan(y/x)
θ = 26°
Answer: False
Explanation: When a switch is closed the circuit is closed and thus the flow of current is on while when the switch is open, the circuit is open, and therefore there will be no flow of current in the circuit.
Answer:
63.57 kg
Explanation:
weight = 140 lbs
Let the mass is m.
1 lbs = 4.45 N
The weight of an object is defined as the force with which our earth attracts the body towards its centre.
Weight is the product of mass of the body and the acceleration due to gravity of that planet.
W = m x g
On earth surface g = 9.8 m/s^2
Now convert lbs in newton
So, 140 lbs = 140 x 4.45 = 623 N
So, m x 9.8 = 623
m = 63.57 kg
Thus, the mass is 63.57 kg.
If you mean beneficial in improving cardiovascular endurance then the best sports would be swimming, running, basketball, rowing and squash.
<span>Water that flows downhill along the earth’s surface is
called runoff. Runoff or also called as surface water runoff or overland flows
is the flow of water when there’s excess water caused by ice melted, rain or
storm. These occur because maybe the rain or the storm pours so hard and quick
that the soil can’t absorb it fastly. If runoff water flows on the ground and
reached a channel, it is called as nonpoint source. One example of nonpoint
source are the canals full of leaves, the water can’t continue flowing because
the leaves stops it.
