Physics
1 answer:
nignag [31]4 years ago
4 0

Answer:

a = 2d / t²

Explanation:

d = ½ at²

Multiply both sides by 2:

2d = at²

Divide both sides by t²:

a = 2d / t²

Answer:

25 watts

Explanation:

Power=work/time

work=force x distance

1000 × 3

=3000 Joules

power= 3000/120

=25 watts

Current is constant at all points in a parallel circuit.<br><br> True<br> False
Sergio [31]
This is false. Current is the speed of the charge, 1 amp of current is 1 coulomb per second. So you can imagine the current of a circuit as the current of a river. In a parallel circuit, the river breaks into two separate streams. Some of the water goes down one river, some goes down the other. However, the total amount of water/coulombs never changes. This means that some of the total current will go down one river, and one the other. However, with less coulombs now the current will decrease. 

Long story short, since there are two paths, the charge will split and depending on the resistance of each parallel stream a different amount of charge will go down each branch.

BMX bicycle rider takes off from a ramp at a point 1.2 m above the ground. The ramp is angled at 40∘ from the horizontal, and th
podryga [215]

Answer:

The ramp lands at an horizontal distance of 3.989 m

Explanation:

Range: Range is defined as the horizontal distance of a projectile from the point of projection to the point where the projectile hits the projection plane again. It is measure in meters (m)

R = U²sin2∅/g..................................... Equation 1

Where R = The horizontal distance from the end of the ramp, U = rider's speed, ∅ = the ramp's angle to the horizontal.

<em>Given: U = 6.3 m/s, ∅ = 40°, g = 9.8 m/s²</em>

<em>Substituting these values into equation 1</em>

<em>R = [6.3²sin2(40)]/9.8</em>

<em>R = (39.69×sin80)/9.8</em>

<em>R = 39.69×0.985/9.8</em>

R = 3.989 m

Thus the ramp lands at an horizontal distance of 3.989 m
