Answer:
because the lumps are just baking soda covered with whatever watery substance you used.
Explanation:
so pretty much inside the lumps is just a bunch of baking soda
Answer:
The vertical component of the acceleration is equal to the acceleration due to gravity g.
Explanation:
Given data,
The initial velocity of the football, u = 31 m/s
The angle of direction of the football with the horizontal, Ф = 41°
In free fall, the vertical component of acceleration always remains the same.
Since the ball is clicked in a particular direction that has a vertical component, then the vertical component of the velocity of the ball is always acted upon by the gravitational force of the earth.
The horizontal component of the velocity of the projectile remains the same because the gravitational force doesn't act in the horizontal direction.
Since the only force is the gravitational force acts on the projectile, the vertical component of the acceleration is equal to the acceleration due to gravity g.
The total power consumption when all three of them are turned on is 1,860 watts. Power=(voltage)x(current). If the service to the household is 120 volts, then the current will be 1860/120=15.5A, which the fuse or breaker will not allow, and they will blow/trip. If the house is in South America or Europe, and the mains service is 240 volts, then the current will be 1860/240= 7.75 Amp, and the fuse or breaker will be 'cool' with that.
Answer:
5.66 × 10⁻²³ m/s
Explanation:
If i assume i can jump as high as h = 2 m, my initial velocity is gotten from v² = u² + 2gh. Since my final velocity v = 0, u = √2gh = √(2 × 9.8 × 2) = √39.2 m/s = 6.26 m/s.
Since initial momentum = final momentum,
mv₁ + MV₁ = mv₂ + MV₂ where m, M, v₁, V₁, v₂ and V₂ are my mass, mass of earth, my initial velocity, earth's initial velocity, my final velocity and earth's final velocity respectively.
My mass m = 54 kg, M = 5.972 × 10²⁴ kg, v₁ = 6.26 m/s, V₁ = 0, v₂ = 0 and V₂ = ?
So mv₁ + M × 0 = m × 0 + MV₂
mv₁ = MV₂
V₂ = mv₁/M = 54kg × 6.26 m/s/5.972 × 10²⁴ kg = 338.093/5.972 × 10²⁴ = 56.61 × 10⁻²⁴ m/s = 5.661 × 10⁻²³ m/s ≅ 5.66 × 10⁻²³ m/s
