Explanation:
Let us assume that piece 1 is
is facing west side. And, piece 2 is
facing south side.
Let
= m and
= 2m. Hence,


= 10.5 m/s


= 10.5 m/s

= 
= 14.84 m/s
or, = 15 m/s
Hence, the speed of the third piece is 15 m/s.
Now, we will find the angle as follows.

= 
= 
= 
Therefore, the direction of the third piece (degrees north of east) is north of east.
It is important because in some way parts of meteoroids made earth which is a part of our solar sysytem
Answer:20ohms
Explanation:
According to ohms law, the current passing through a metallic conductor is directly proportional to the potential difference across its ends. Mathematically,
V = IR where;
V is the potential difference
I is the current
R is the resistance
Given current I that the iron carries = 6.0A
Voltage source (the Emf) = 1.2×10²V
resistance R = V/I
R = 120/6
R = 20ohms
Therefore the resistance of the steam iron is 20ohms
Answer:
Explanation:
Given that the velocity of the river is 1.50m/s due east.
The velocity of the boat with respect to the river is 10.0 m/s due north .
The width of the river is 325 m.
Note that the velocity of the boat will help in crossing the river.
Hence, speed = distance/time
Speed = 10.0 m/s
Distance = 325 m
Time = ?
10 = 325/time
Time = 325/10
Time = 32.5s
Hence in 32.5s the horizontal distance traveled by boat will be
= 1.50m/s × 32.5s
= 48.75m
