Answer:
Acceleration = 0.5m/s²
Explanation:
Given the following data;
Final velocity = 5m/s
Time = 10 seconds
Since the spider started from rest, its initial velocity is equal to 0m/s
To find the acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in 
v and u is final and initial velocity respectively, measured in 
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = 0.5m/s²
answer
18000 J
explanation
the lightbulb dissipates 5W of power
P = ΔE / Δt
rearrange to solve for energy
ΔE = PΔt
P = 5W
t = 1 hour = 60 minutes = 3600 seconds
ΔE = 5 * 3600
ΔE = 18000 J
From km 240 to km 300 there are 60 km.
The time to travel 60 km at 80km/h is t = d/V = 60km / 80 km/h = 3/4 h.
That is 45 minutes. Then the car will arrive at 7:30 + 45 min = 8:15.

Answer:
move at constant velocity.
Explanation:
Newton's first law (also known as law of inertia) states that:
"when the net force acting on an object is zero, the object will keep its state of rest or if it is moving, it will continue moving at constant velocity".
In the case of the probe, friction in deep space is negligible, therefore when the engine is shut down, there are no more forces acting on the probe: the net force therefore will be zero, so the probe will move at constant velocity.
