Answer:
hydrogen gas along with some helium and a mixture of trace elements
Answer:
d, the awnser all of the above
A marble rolls off a tabletop 1.15 m high and hits the floor at a point 4 m away from the edge of the table in the horizontal direction,
- t= 0.45 seconds.
- V=2.22m/s
- VT=4.95 m/s
This is further explained below.
<h3>What is its speed when it hits the floor...?</h3>
Generally, the equation for motion is mathematically given as
S= ut + 0.5at²
Therefore
y = Voy t + 0.5gt^2
1 = 0.5x 98 x 6²
1=4.9t^2
t= 0.45 seconds.
b) Horizontal motions are uniform.
V=Horizontal displacement/time
V=1/0.45
V=2.22m/s
C)
Vx: 2.22 m/s At bottom,
Vy² = Voy² + 2as
Vy² = 2x95x1
Vy² = 19.6
Total velocity
VT=4.95 m/s

Explanation:
A crystalline solid that conducts current under certain conditions
Answer: 1A
Explanation: for an ideal transformer, the relationship between number of turns and current is given below as
Ip/ Is = Ns/ Np
Where Ip = current in primary loop = 3A
Is = current in secondary loop =?
Np = number of turns in primary loop = n
Ns = number of turns in secondary loop = 3n
By substituting the parameters, we have that
3/Is = 3n/n
3/Is = 3
3 = 3 × Is
Is = 3/3 = 1A
Current in the secondary loop is 1A
