Answer:
<h2>1.17 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>1.17 m/s²</h3>
Hope this helps you
Answer:
Photosynthesis is the pocess by which green plants make their own food.
b. sunlight, glucose, water, altra-violet ray as catalyst
Its average speed, pretending that it traveled at a constant speed, is
v = s / t
= 600 m
5 x 60 s
= 2 m/s
but to be a velocity it needs a direction as well as a speed.
( Sorry. Can’t find a division line to put between the 600 m and the 5 x 60 s )
Answer:
10.21°C
Explanation:
From the question,we are given;
- Quantity of heat = 32,000 Joules
- Mass of water = 750 g
- Specific heat capacity of water = 4.18 J/g°C
We are required to calculate the change in temperature;
- We need to know that quantity of heat is calculated by multiplying mass by specific heat then by change in temperature.
- That is;
Q = m × c × ΔT
Rearranging the formula;
ΔT = (Q ÷ (m × c))
= 32,000 J ÷ (750× 4.18 J/g°C)
= 10.21°C
Therefore, the change in temperature is 10.21°C
